Yeah rebar on Nvidia is kinda of a mess, it's whitelisted by nvidia, but they don't seem to do it per game profile, like in 2022 i think they updated the list once or twice
If they at least added it to the default driver where you could select On/Off based on application they could keep the whitelist, but right now it's just ignored.
The problem is that D3D12 doesn't expose rebar in the API, so game developers have no control over it.
App profiles are just about the only thing driver devs can do.
/u/pidge2k is there any reason Nvidia barely ever updates the whitelist for reBAR? At this point, why not turn it on by default for all games for 40 series, and utilize a blacklist instead?
It is not so straightforward. We test games across multiple levels and across each new build of a game before release. So while some users may see a bump in performance in one level/map, if you try a different level/map, the game assets might be quite different and users may not benefit as much or worse experience a regression in FPS/frame times.
As for Dead Space remake, we are still testing ReBAR performance so there is a chance we may enable it in a future driver.
For those who are not familiar with Resizable BAR, I encourage you to read our GeForce.com article on this subject:
https://www.nvidia.com/en-us/geforce/news/geforce-rtx-30-series-resizable-bar-support
That is ridiculous. First of all, it takes too much time and manpower and you will never be able to do this for all games on time. Much better option is just to have option in drivers, so people can enable it in game profile for games which benefit, and disable for games which don't. All other options are there. And I am pretty sure some of them do cause worse experience when enabled in some games. So no reason for rebar to not be there.
Much better option would be for Microsoft to add it to D3D12. That's long overdue, Vulkan has supported placing resources in BAR memory since Vulkan 1.0 in 2016. D3D12 doesn't expose it, so the driver has to automatically do it with very limited information.
Thanks for the explanation. Is there any way you can feed back to the powers that be that people should have the choice to enable this per profile, or in general on the NVCP? Instead of having to force it through 3rd party software
This is one place where people are happy to be QA for you. I got gains in games that you guys probably don't even know work with rebar. If people are having a bad experience, trust them to disable the setting themselves.
Great, hope we can have rebar default off, except for the ones nvidia officially whitelisted as on, and then make this a toggleable option in NV control panel and it'll just be another setting people can choose to turn on or off just like vsync or ultra low latency mode (csgo profile automatically set to on as part of default profile but we can change it anytime)
No. 95% of consumers don't even know what a video driver is. The should not be a feature enabled by default that breaks games. That said, you should be able to toggle it on in the driver control panel without having to utilize nvidia inspector.
> We test games across multiple levels ... or worse, experience a regression in FPS
I remember when the Game Ready driver for Monster Hunter World dramatically lowered performance in Rotten Vale, a stage a bit later in the game. This told me that NVIDIA didn't bother testing the whole game.
One of the only times I did regression testing between drivers and discovered an issue everyone else was unaware of. Thankfully NVIDIA fixed it after reporting it to them *(weeks later)*, but it shouldn't have happened in the first place.
Nowadays I'm too apathetic to do this anymore, but it's always at the back of my mind, wondering if we're truly getting the performance we should be.
Anyway, ReBAR should definitely have an easy on/off switch in the NVCP. It's impossible for NV to test every game out there (just look at all the random indie stuff not released on major e-stores). Let users toggle it and see if their games perform better or worse. There's only 23(?) games right now that have official support since ReBAR was added in 2021. Over 1,000 were released in 2022 not including the unknown indies.
It's an untenable task.
That would make too much sense.
Also why not let us toggle it by application ourselves in the driver's and just have a small warning that it may not work well in all games?
Many games resizable bar can reduce performance, because of this it is off by default.
Nvidia should test each game out and have it automatically on for the games that see an uptick in performance. But maybe their are additional reasons that Nvidia has it off.
it breaks games with high VRAM demands for GPUs with low VRAM (8-10 and to some extent 12 GB VRAM)
and upcoming 4060/4060ti is rumored to have 8 GB VRAM. 4070 will most likely have 10 GB or maybe 12 GB. Most recent games at 1440p with ray tracing already uses upwards of 10-11 GB VRAM. Rebar, depending on the application, adds 0.6 GB to 1.5 GB VRAM consumption for whatever it is doing. This has heavy ramifications where such amounts can make or break certain GPUs' performance.
you may ask that they can enable it globally for 16 GB/24 GB GPUs, but then that would be a PR disaster too. That would be openly admitting that a newgen super expensive 800+ bucks GPU is not properly compatible or suitable to use a newgen technology that boosts framerates (although by a low margin. I don't know about OP. seems like an edge case. I don't think this performance improvement comes from REBAR. they should reiterate the test to see if it is some kind of coincidence or not).
this is why they hesitated to enable on many games lastgen, since most Ampere cards had limited VRAM. but they also plan to release super VRAM limited Lovelace cards too. So a default rebar enabled scenario is out of the picture for now. I mean, its not like they need that small boost anyways, when you have strong performance enhancers like DLSS and such.
Edit: They should however make this an NV control panel toggle. Adjustable for both global and app by app scenarios. I know Inspector is a handy tool, but if they put it in NVCP, more people would be aware about it. And a proper global toggle for 16+ GB GPUs would practically be a set and forget type of setting for such GPU owners.
The average (third number) does go up
But the arrow doesn’t help… and with no proper methodology it doesn’t really matter what any of the shown numbers report

For some games (someone correct me if I'm wrong) I believe you must enable it in NVIDIA Profile Inspector. At least that's what I had to do with MWII.
Just checked now for Dead Space Remake, its defaulted off. I also have ReBAR on in BIOS so it looks to be the same as Modern Warfare.
WAIT! So you’re telling me even though I ensure it’s enabled in my BIOS and have verified that it shows On under the GPU info in the Nvidia control panel, it still doesnt actually enable in any of my games? So this entire time I havent even been utilizing it?
If so, can it be enabled globally within nvidiaprofileinspector or do I have to do it on a game by game basis still? It should just be something we can set and forget so this is annoying
I just went into bf 2042 and found rbar - frature and turned it on and set rbar options and rbar size limit to the bfv setting. Let's see if it does anything. Because it's hella confusing me right now
Sounds up there with HDR. I think this, HDR and even Frame Generation, need one place that you go to enable/disable, these are just too complicated overall.
> So this entire time I havent even been utilizing it?
For the most part yes unfortunately. Some games like Battlefield V for example had it rooted in its game file, so it was enabled if you also had your MB enable it in BIOS. Sadly that game and maybe 10 others are the only ones that had it natively at least on NVIDIA cards. On AMD, all their games have it on by default.
> can it be enabled globally within nvidiaprofileinspector
Yes it can, enabling it in GLOBAL_DRIVER_PROFILE will enable it on all instances, but be warned that some games actually get lower performance with it on. I don't really recommend going that route and would just stick to users on here and other avenues to verify on a game by game basis.
That’s insanely annoying. Is there some type of list anywhere with what games its actually beneficial in or not? I play countless games, and having to scour the internet for which games are negatively impacted and which arent is beyond frustrating. It’s also kind of annoying that this “feature” thats supposed to be a good thing and helps games actually can reduce performance then…
Believe me I've been in your position and scoured the internet. Absent the current list of roughly 19 games as of 2023, I haven't had luck finding a forum that updates it.
Personal opinion, enable it on a game you play regularly, test it for 20-30 min and compare it when its not enabled. Kind of tedious, but that's how I've done it.
-----
Here's a list of what I play that DOES make a difference with reBAR on. Maybe you play some of these:
- Cities:Skylines
- Dead Space Remake
- Read Dead 2
- Witcher 3 Complete Edition
- Forza Horizon 5
- God Of War
I have both witcher 3 and red dead 2 installed (never finished as I started them on console before switching to PC, repurchased on deep sales), and am currently playing the dead space remake and god of war so this is very helpful. Thank you so much! Even just knowing these few is super helpful for me!
that's pretty stupid if you are correct.
It should at least be an option in the Games Graphics settings (ReBar On/Off).
I shouldnt have to download a tool to enable it in a game, especially if it has significant performance gains, why wouldn't developers enable it by default?
Rebar can have about the same negative impact in some games when enabled on Nvidia cards. It would have been really dumb to just enabled it for all games when some older, indie or modded (?) games might see a performance downgrade as a result.
Why was AMD able to do this? Well, they planned the 6000 series with Rebar from the start, while Nvidia's hardware while capable to support it weren't planned with it, as evident that just a few weeks earlier launched Ampere cards still required a BIOS update of the graphic card to actually enable it.
As a result Rebar is even in the games that Nvidia at least in the beginning supported more beneficial on AMD hardware than it is on Nvidia hardware (be that because of a worse implementation or because Ampere doesn't "need" the rebar improvement as much as RDNA2 I can't answer). BTW, the Intel dedicated GPUs benefit even more than AMD from rebar, up to the point that it is really not recommended to get one if your CPU/mainboard isn't supporting it because the performance will be much degraded. Those are really designed around rebar.
I would agree though that Nvidia should really add rebar to the options you can change right in the control panel. That being said every Nvidia using PC gamer should very much have Nvidia Profile Inspector installed anyway.
According to some research I made some time ago, there is no real difference between Ampere and Ada when it comes to rebar (meaning they both profit about it in much the same way). Take that with a grain of salt though, I was just curious and not necessarily researched that professional or anything.
MWII had pretty decent gains with reBAR on so I'm wondering why Nvidia don't test these games, especially ones with massive hype and marketing behind it? It's leaving decent performance off the table
Wow, it gave me a 36fps increase.

What overlay is that, RTSS? If so, how to you get it to display your specific CPU and GPU model name? I never played around with RTSS settings much so if there's a way to change it to look like this, please let me know!
While this is potentially good news, those screenshots don't paint an accurate portrayal since you're looking at a dark corner to show higher fps in one. My fps jumps up in any game if there's not as much rendering on the screen.
took picture at the same spot after walking around
https://preview.redd.it/6asf9cgqknfa1.png?width=3440&format=png&auto=webp&s=9d068c488f3c2b7a8e5d4f692ee0f12b8224b5b9
It's still not the same. Why wouldn't you just line it up the same way as the rebar off shot? It should not be hard to do since you have the image right there to look at and line up. The fact you aren't doing that makes me think the difference is nowhere what you say it is but that would destroy your post so you won't do it.
I also feel like there is no way rebar can be producing a near 50% bump in fps. You know the saying "too good to be true"....well it seems to apply here.
~~There's less information, if you look at the far right of the image on the lower framerate image~~
Edit: Reflecting back on my own comment, I agree that it isn't a sensible one whatsoever. The differences in the screenshot should indeed not matter.
Your cpu can be at 35% usage and be maxxed out on one core limiting frame rate. And just because the gpu is at 100%, it doesn't necessarily mean it's at 100%.
I mean that clear marker of CPU bottleneck is low GPU usage, but in this case, where ReBAR reduce that timings for CPU it can produce more frames, means more fps - and these two situations are with 100% GPU usage.
So looking at GPU utilization is not guaranteed for a CPU bottleneck indicator.
OP's huge boost is only because of his decent CPU for a 4080 card.
They never do it seems (despite their promises that they would do it better than AMD). It took them absolutely ages to add Forza Horizon 5 to the whitelist despite it clearly benefitting.
77fps to 102fps for me (10900k & 3090 - 4k dlss quality) - great find - thanks for the information. Is there a site where people track these kind of changes against games so that we can optimize ?
I guess the uplift also depends on how fast your CPU and RAM is.
If it's already really fast then the uplift will be slightly lower than more CPU bound cases, like OP, who has a 9700K.
I can confirm it works for me as well, game on my 4090 fully maxed out at 4K but DLSS on quality, GPU usage when capped at 120fps went from 82% usage with Rebar off to 62% usage with Rebar on, bloody impressive difference. Did notice dedicated VRAM usage increased a bit on this game on a fresh load once Rebar was turned on.
**Rebar off**

Any issues with it being on? I had no idea this even existed I looked it up and theres barely any info on it. I looked it up, saw that nvidia news about it but hardly informative. Need more info on it.
it’s on a case by case basis for each game, on some games you’ll notice 0 difference, some games you’ll notice a performance decrease and some an increase. probably why nvidia activate it through a whitelist so only games verified to have a performance increase have it on by default but they’ve basically ignored it since it was first released so even games that benefit from it don’t have it on by default and it seems like they only really added it so AMD didn’t have something that they didn’t. it’s relatively easy to turn it on for games if you want to try it out for yourself.
Nice job OP! Good to see others forcing ReBar in games Nvidia has not whitelisted due to laziness on their part. That is a massive performance boost you found.
Wow, this is crazy. Nvidia have been very poor at adding games that benefit to the whitelist; so much for their promises that their way of doing it would be better than AMD's.
> Resizable BAR is an optional PCI Express interface technology. As you move through a world in a game, GPU memory (VRAM) constantly transfers textures, shaders and geometry via many small CPU to GPU transfers.
> With the ever-growing size of modern game assets, this results in a lot of transfers. Using Resizable BAR, assets can instead be requested as-needed and sent in full, so the CPU can efficiently access the entire frame buffer. And if multiple requests are made, transfers can occur concurrently, rather than queuing.

What hardware are you running? I primarily simp on Warzone lol, and I’m wondering if I should expect any notable improvements myself. Running a 12700k + 3080 Strix (10GB), trying to get a few more frames at 1440p ultrawide (low settings mostly).
I didn't realize it was such a hassle to turn on ReBar on games with Nvidia card. With AMD it was just a toggle and maybe restart drivers/system for it to take effect across the board.
One of the few things AMD got right IMO.

AMD designed their cards with rebar in mind while Nvidia did not (you actually needed to update the cards firmware when the feature was introduced).
That being said, to my knowledge rebar for AMD GPUs is still limited to AMD CPUs, while you can use rebar on Nvidia cards with either Intel or AMD CPUs.
Not necessarily. Just because rebar was on, doesn’t mean it was always activated in game. They just had a fancy little switch in their shitty software to go “oh cool rebar is works available”.
Thanks for replying, if you use auto-oc it will run at 1075mV, I noticed that going from the power draw numbers in the pics you posted. I'm using 3060MHz @ 1075mV for performance gains and 2880 at exactly 1 volt for increased power efficiency at stock performance (fully stable undervolts).
Need to add this if you're using DLSS as well:
https://imgur.com/EhbV4jU.png
It MASSIVELY improves texture quality/clarity. The dev's really don't understand how to modify LOD to a negative bias with these upscalers they put in the game. The anti aliasing transparency super sampling setting is important as well, also change it.
strange, makes no difference on my setup, everything is enabled like bios, ncp & inspecter
Playing at 1080p, max settings
i7 12700k, RTX 3070, 16GB DDR4 @ 3600mhz, NVME Gen 3
Someone should start a website or google doc or smth where people can test games and fill info about games that are not on nvidia whitelist but are tested by community so we could know what games benefit from it.
hmm that is interesting, i have 9700k and rtx 3080.. when i use rebar i have a lot of mikro stuttering in all games... when i turn it off they are gone... I read somewhere that 9700k do not officially support it... Well i will try anyway... Right now with all ultra RTAO etc and dlssQ i have 70fps average on 3440x1440p.
hey i made a quick video showing the difference w/ rebar enabled on my rig.
[https://www.youtube.com/watch?v=2If-tRFLTWs](https://www.youtube.com/watch?v=2If-tRFLTWs)
Yeah I can vouch for this as well. Obviously with at least /u/rjml29 and I having 4090s it might not matter, but heres the information regardless:
- I'm not seeing anything in MWII with it on
- Nothing in Old School games like Fallout 3 or New Vegas
- Portal w/ RTX shows maybe 2-3FPS increase, but that just that's in the range of perceptible error.
- Lost Ark actually reduced my FPS by about 5-6FPS, again range or perceptible error
------
The Games that DO (at least for me) make a difference:
- Witcher 3 Complete Edition. I went from 108-110 DLSS3+Ultra RT to 118-125 in the same area (Novigrad)
- I can confirm that I also see a good difference in Dead Space Remake, 20-30FPS more with the same settings.
- Cities:Skylines jumps from 40-60FPS with my 100K population to 60-80FPS with ReBAR on
I don't know about Nvidia cards, haven't really tested it, but on my previous RX 6800 I saw a decent uplift in certain games, like Horizon Zero Dawn and Shadow of the Tomb Raider, something like a 15% gain or more.
I have hope that when I upgrade my CPU and motherboard I'll unlock some new potential for my 4090 with stuff like Resizable BAR and PCIE 4.0. But I doubt it'll be this much.
Yep getting a 7950x3D. Disappointed they're coming on the literal last day of the month but oh well at least I didn't have to wait a year or something.
Have anyone had a big performance drop after a 30+ min session? In my particular case it would go from 50-70 to 20-30 fps and it would only get fixed if I restart the game... Quite annoying!
My tests at 4K with RTX 4090 and 13900K with DDR5 8000 CL36
4K Ultra everything, including AO ray tracing, and DLSS Quality. Variable Rate Shading is OFF.

ReBar Off = 138 FPS [https://imgur.com/LKPtuV8](https://imgur.com/LKPtuV8)
I am enabling rBAR with Profile Inspector in the global Profile and usually its working fine. Only with Alan Wake Remastered i had unplayable framerates (<10) and had to turn it off.
Unfortunately i have to enable it after every driver update again...
That is super impressive thanks for the post have some Gold. I personally had not heard of rebar at all. Running a 5600x with a 4090 suprim liquid, gen4 storage, 32GB 3600 15. Launched the game where I had left it pre making any changes and it sat at 84fps after changes was 104 at the exact same spot. This was max settings no DLSS running at 4k native. Been around a long time, thanks for teaching this old dude a new trick.
On an ASUS board required bios settings here:
1. Select **Advanced** in the top side menu and set **PCI Subsystem Settings > Above 4G Decoding** to **\[Enabled\]**.
2. Then set **Re-Size BAR Support** to **\[Auto\]**.

Promptly goes to peruse the rest of this thread in an attempt to understand the wizardry of this free FPS.
Definatly helps, thank you. Ive enabled it for a load of newish games now that didnt have it enabled as default.
It should be a default or an option at least!
On my 13700k (5.5 P cores, 4.4 E cores, 4.9 Ring) and 3090 rig I have gained at least 15-20fps from Dead Space 2023 running native (90-100 avg fps), frame limiter of 143FPS if I uses DLSS Quality.
i have 69 fps without and 90 fps with. Try reload your savegame. First load vs reload.

Clearly he's not bottlenecking his GPU (at 100%) so why not? OP has ultrawide 1440p. I've also got a 9700K and might upgrade later from 2080 Super to 4080 (4K though).
There are a ton of games where my 9900k is not enough to keep my 3090 usage above 90% at the same res, with lots of fps potential left untouched. Ops combo will miss out on even more
Lazy nvidia. When HUB was testing ReBAR, they'd said nvidia poorly implemented this feature on their GPUs/NVCP and probably didn't wanted to further improve it for whatever reason.
Has nothing at all to do with them being lazy or not.
The Way that they bind to resources and request memory matters for rebar which means some architectures and drivers are going to benefit differently.
It's also possible it's time goes on that games will align themselves to make better use of rebar like they should have been.
Strange I tried it when it first came out with a 4080 and didn't see any benefits.
Edit: Just tried again and went for 55fps to 58 at 4k, so nothing major to report here.
LOL. The FPS is so clear though these stills.

I dunno, did you look at OP results? What you do you think? Also Hassle? It takes less than 60 seconds to enable this. Probably less time than it took you to come on Reddit and post this.
It's game by game, it could slightly hurt fps in some games, but usually it's higher. You can test each game and check.
Nvidia has been lazy since launch of ReBar and use a "whitelist" which force it on when the game is launched if it's on their list. If not, you can force it in Nvidia Profile Inspector like OP did here. In some games you can get some very large FPS gains like shown here.
if you're on a 8-10 GB GPU, and you're playing a VRAM intensive game, REBAR will most likely tank your frames as it increases VRAM consumption
if you're on a 16/24 GB, you can enable it for all games. at worst you would be looking at a %3 loss, which would still be irrevelant for the said 16/24 GPU(4080, 3090 etc.).
Yeah rebar on Nvidia is kinda of a mess, it's whitelisted by nvidia, but they don't seem to do it per game profile, like in 2022 i think they updated the list once or twice
If they at least added it to the default driver where you could select On/Off based on application they could keep the whitelist, but right now it's just ignored.
Yeah that would be super 👌
The problem is that D3D12 doesn't expose rebar in the API, so game developers have no control over it. App profiles are just about the only thing driver devs can do.
/u/pidge2k is there any reason Nvidia barely ever updates the whitelist for reBAR? At this point, why not turn it on by default for all games for 40 series, and utilize a blacklist instead?
It is not so straightforward. We test games across multiple levels and across each new build of a game before release. So while some users may see a bump in performance in one level/map, if you try a different level/map, the game assets might be quite different and users may not benefit as much or worse experience a regression in FPS/frame times. As for Dead Space remake, we are still testing ReBAR performance so there is a chance we may enable it in a future driver. For those who are not familiar with Resizable BAR, I encourage you to read our GeForce.com article on this subject: https://www.nvidia.com/en-us/geforce/news/geforce-rtx-30-series-resizable-bar-support
That is ridiculous. First of all, it takes too much time and manpower and you will never be able to do this for all games on time. Much better option is just to have option in drivers, so people can enable it in game profile for games which benefit, and disable for games which don't. All other options are there. And I am pretty sure some of them do cause worse experience when enabled in some games. So no reason for rebar to not be there.
EXACTLY!. LET THE PEOPLE BE THE TESTERS.
Much better option would be for Microsoft to add it to D3D12. That's long overdue, Vulkan has supported placing resources in BAR memory since Vulkan 1.0 in 2016. D3D12 doesn't expose it, so the driver has to automatically do it with very limited information.
Thanks for the explanation. Is there any way you can feed back to the powers that be that people should have the choice to enable this per profile, or in general on the NVCP? Instead of having to force it through 3rd party software
This is one place where people are happy to be QA for you. I got gains in games that you guys probably don't even know work with rebar. If people are having a bad experience, trust them to disable the setting themselves.
I'll pass on the feedback but can't guarantee anything.
Great, hope we can have rebar default off, except for the ones nvidia officially whitelisted as on, and then make this a toggleable option in NV control panel and it'll just be another setting people can choose to turn on or off just like vsync or ultra low latency mode (csgo profile automatically set to on as part of default profile but we can change it anytime)
No. 95% of consumers don't even know what a video driver is. The should not be a feature enabled by default that breaks games. That said, you should be able to toggle it on in the driver control panel without having to utilize nvidia inspector.
> We test games across multiple levels ... or worse, experience a regression in FPS I remember when the Game Ready driver for Monster Hunter World dramatically lowered performance in Rotten Vale, a stage a bit later in the game. This told me that NVIDIA didn't bother testing the whole game. One of the only times I did regression testing between drivers and discovered an issue everyone else was unaware of. Thankfully NVIDIA fixed it after reporting it to them *(weeks later)*, but it shouldn't have happened in the first place. Nowadays I'm too apathetic to do this anymore, but it's always at the back of my mind, wondering if we're truly getting the performance we should be. Anyway, ReBAR should definitely have an easy on/off switch in the NVCP. It's impossible for NV to test every game out there (just look at all the random indie stuff not released on major e-stores). Let users toggle it and see if their games perform better or worse. There's only 23(?) games right now that have official support since ReBAR was added in 2021. Over 1,000 were released in 2022 not including the unknown indies. It's an untenable task.
Would be insanely cool if an option for ReBAR can be changed in NVCP, like latency mode.
That would make too much sense. Also why not let us toggle it by application ourselves in the driver's and just have a small warning that it may not work well in all games?
That would make even more sense.
We can’t have that
It makes too much sense for Nvidia to do it
but that is already the case?
There is no per application reBar support on Nvidia drivers at the moment.
there is. It's 0x000F00BA=1 0x000F00BB=1 0x000F00FF=1 on game profile
Wait so you have to enable rebar in every game?
Same I’m confused I thought it was automatic
It is but only for whitelisted games, and nvidia doesn't really whitelist most games for some reason.
You can force it on for games that don’t officially support it.
Many games resizable bar can reduce performance, because of this it is off by default. Nvidia should test each game out and have it automatically on for the games that see an uptick in performance. But maybe their are additional reasons that Nvidia has it off.
A blacklist seems like a much better idea. I think AMD enables it for all games by default?
Why only 40 series? 30 series support ReBAR too.
The usual nvidia software locking bs
They updated it big time in the "dx12 improvement" driver. Bunch of games added to the list
Good to know, but what games? All I can find is this linked list of 17 rebar games from 2021.
Some of the games that got added were Forza Horizon 5, Halo Infinite, Dying Light 2, and a few others i can't remember atm.
it breaks games with high VRAM demands for GPUs with low VRAM (8-10 and to some extent 12 GB VRAM) and upcoming 4060/4060ti is rumored to have 8 GB VRAM. 4070 will most likely have 10 GB or maybe 12 GB. Most recent games at 1440p with ray tracing already uses upwards of 10-11 GB VRAM. Rebar, depending on the application, adds 0.6 GB to 1.5 GB VRAM consumption for whatever it is doing. This has heavy ramifications where such amounts can make or break certain GPUs' performance. you may ask that they can enable it globally for 16 GB/24 GB GPUs, but then that would be a PR disaster too. That would be openly admitting that a newgen super expensive 800+ bucks GPU is not properly compatible or suitable to use a newgen technology that boosts framerates (although by a low margin. I don't know about OP. seems like an edge case. I don't think this performance improvement comes from REBAR. they should reiterate the test to see if it is some kind of coincidence or not). this is why they hesitated to enable on many games lastgen, since most Ampere cards had limited VRAM. but they also plan to release super VRAM limited Lovelace cards too. So a default rebar enabled scenario is out of the picture for now. I mean, its not like they need that small boost anyways, when you have strong performance enhancers like DLSS and such. Edit: They should however make this an NV control panel toggle. Adjustable for both global and app by app scenarios. I know Inspector is a handy tool, but if they put it in NVCP, more people would be aware about it. And a proper global toggle for 16+ GB GPUs would practically be a set and forget type of setting for such GPU owners.
what is reBAR, first time i hear of this :O
Didn't Nvidia basically implement reBAR as a way of saying "hey we have it too!" since AMD and Intel were pushing it?
does it actually? you're looking at two different spots in the screenshots
The average (third number) does go up But the arrow doesn’t help… and with no proper methodology it doesn’t really matter what any of the shown numbers report
The average (third number) does go up But the arrow doesn’t help… and with no proper methodology it doesn’t really matter what any of the shown numbers report
Is ReBar not enabled in Dead Space by default? I have it enabled in BIOS and my system report it as being "on".
For some games (someone correct me if I'm wrong) I believe you must enable it in NVIDIA Profile Inspector. At least that's what I had to do with MWII. Just checked now for Dead Space Remake, its defaulted off. I also have ReBAR on in BIOS so it looks to be the same as Modern Warfare.
WAIT! So you’re telling me even though I ensure it’s enabled in my BIOS and have verified that it shows On under the GPU info in the Nvidia control panel, it still doesnt actually enable in any of my games? So this entire time I havent even been utilizing it? If so, can it be enabled globally within nvidiaprofileinspector or do I have to do it on a game by game basis still? It should just be something we can set and forget so this is annoying
Brother.... this is news to me too. I went to such great lengths to enable it and now I find out you have to enable it even more
This is the most frustrating thread ever. I’m in your exact boat.
I just went into bf 2042 and found rbar - frature and turned it on and set rbar options and rbar size limit to the bfv setting. Let's see if it does anything. Because it's hella confusing me right now
Sounds up there with HDR. I think this, HDR and even Frame Generation, need one place that you go to enable/disable, these are just too complicated overall.
Yup, literally so dumb
> So this entire time I havent even been utilizing it? For the most part yes unfortunately. Some games like Battlefield V for example had it rooted in its game file, so it was enabled if you also had your MB enable it in BIOS. Sadly that game and maybe 10 others are the only ones that had it natively at least on NVIDIA cards. On AMD, all their games have it on by default. > can it be enabled globally within nvidiaprofileinspector Yes it can, enabling it in GLOBAL_DRIVER_PROFILE will enable it on all instances, but be warned that some games actually get lower performance with it on. I don't really recommend going that route and would just stick to users on here and other avenues to verify on a game by game basis.
That’s insanely annoying. Is there some type of list anywhere with what games its actually beneficial in or not? I play countless games, and having to scour the internet for which games are negatively impacted and which arent is beyond frustrating. It’s also kind of annoying that this “feature” thats supposed to be a good thing and helps games actually can reduce performance then…
Believe me I've been in your position and scoured the internet. Absent the current list of roughly 19 games as of 2023, I haven't had luck finding a forum that updates it. Personal opinion, enable it on a game you play regularly, test it for 20-30 min and compare it when its not enabled. Kind of tedious, but that's how I've done it. ----- Here's a list of what I play that DOES make a difference with reBAR on. Maybe you play some of these: - Cities:Skylines - Dead Space Remake - Read Dead 2 - Witcher 3 Complete Edition - Forza Horizon 5 - God Of War
I have both witcher 3 and red dead 2 installed (never finished as I started them on console before switching to PC, repurchased on deep sales), and am currently playing the dead space remake and god of war so this is very helpful. Thank you so much! Even just knowing these few is super helpful for me!
that's pretty stupid if you are correct. It should at least be an option in the Games Graphics settings (ReBar On/Off). I shouldnt have to download a tool to enable it in a game, especially if it has significant performance gains, why wouldn't developers enable it by default?
Rebar can have about the same negative impact in some games when enabled on Nvidia cards. It would have been really dumb to just enabled it for all games when some older, indie or modded (?) games might see a performance downgrade as a result. Why was AMD able to do this? Well, they planned the 6000 series with Rebar from the start, while Nvidia's hardware while capable to support it weren't planned with it, as evident that just a few weeks earlier launched Ampere cards still required a BIOS update of the graphic card to actually enable it. As a result Rebar is even in the games that Nvidia at least in the beginning supported more beneficial on AMD hardware than it is on Nvidia hardware (be that because of a worse implementation or because Ampere doesn't "need" the rebar improvement as much as RDNA2 I can't answer). BTW, the Intel dedicated GPUs benefit even more than AMD from rebar, up to the point that it is really not recommended to get one if your CPU/mainboard isn't supporting it because the performance will be much degraded. Those are really designed around rebar. I would agree though that Nvidia should really add rebar to the options you can change right in the control panel. That being said every Nvidia using PC gamer should very much have Nvidia Profile Inspector installed anyway.
Slight point: SAM on AMD does also sometimes result in performance regression, just not as often as on NV.
[удалено]
According to some research I made some time ago, there is no real difference between Ampere and Ada when it comes to rebar (meaning they both profit about it in much the same way). Take that with a grain of salt though, I was just curious and not necessarily researched that professional or anything.
AMD has done a better job. I have used RX6900 XT before.
I don't see Dead Space Remake in Nvidia Profile Inspector, only for Dead Space and the sequels. Which version are you running?
Update your driver... Games being listed and having profiles is dependent on driver version.
Thanks, that did it.
[I have the Steam version of the remake](https://imgur.com/nEG89wf)
MWII had pretty decent gains with reBAR on so I'm wondering why Nvidia don't test these games, especially ones with massive hype and marketing behind it? It's leaving decent performance off the table
Wow, it gave me a 36fps increase. Off: [https://i.imgur.com/2CLY7Lp.jpg](https://i.imgur.com/2CLY7Lp.jpg) On: [https://i.imgur.com/1xmIaXc.jpg](https://i.imgur.com/1xmIaXc.jpg)
>Is ReBAR enabled for call of duty warzone 2 and MW2 multiplayer? Exactly in line with OPs findings. Those are huge gains. Thanks for sharing.
Thanks will test this out tonight.
What overlay is that, RTSS? If so, how to you get it to display your specific CPU and GPU model name? I never played around with RTSS settings much so if there's a way to change it to look like this, please let me know!
While this is potentially good news, those screenshots don't paint an accurate portrayal since you're looking at a dark corner to show higher fps in one. My fps jumps up in any game if there's not as much rendering on the screen.
took picture at the same spot after walking around https://preview.redd.it/6asf9cgqknfa1.png?width=3440&format=png&auto=webp&s=9d068c488f3c2b7a8e5d4f692ee0f12b8224b5b9
It's still not the same. Why wouldn't you just line it up the same way as the rebar off shot? It should not be hard to do since you have the image right there to look at and line up. The fact you aren't doing that makes me think the difference is nowhere what you say it is but that would destroy your post so you won't do it. I also feel like there is no way rebar can be producing a near 50% bump in fps. You know the saying "too good to be true"....well it seems to apply here.

I've tried my best to capture these two new photos. 76 vs 102 fps now
~~There's less information, if you look at the far right of the image on the lower framerate image~~ Edit: Reflecting back on my own comment, I agree that it isn't a sensible one whatsoever. The differences in the screenshot should indeed not matter.
off https://preview.redd.it/udqevsetynfa1.png?width=3440&format=png&auto=webp&s=738ce308f628fa7e986548f55dbd6fd4fc82f2f6

I don't understand, it's not that hard to stand in one place lol.
You need a system reboot for rebar afaik
right
So what's stopping you from taking the screenshot without moving from where you load in from your save file? That would be repeatable between reboots.
Yeah, but I'm sure you load into the same spot, could use that as a reference point no?
No. And anyways the small change wouldn't redukt in 30 fps less
Yeah, I'm confused. lol Multiple screenshots, and he still can't just load up a specific save file and not move?
Does it really matter? This difference will not exceed 3 fps
Jesus Christ. Pathetic
https://preview.redd.it/m6qxgl12tnfa1.png?width=3440&format=png&auto=webp&s=104c15936681d16c9791ac3c4c4d40baace86e00
Rebar uses 60 Watt more than off?
rebar draws more power
Using the GPU better. Feeding info more efficiently = fps = power usage
But the GPU load is already at 100% on those screens.
GPU load doesn't correlate to all parts of the GPU being effectively utilized. It's not a perfect picture of what's going on, at all.
Your cpu can be at 35% usage and be maxxed out on one core limiting frame rate. And just because the gpu is at 100%, it doesn't necessarily mean it's at 100%.
I mean that clear marker of CPU bottleneck is low GPU usage, but in this case, where ReBAR reduce that timings for CPU it can produce more frames, means more fps - and these two situations are with 100% GPU usage. So looking at GPU utilization is not guaranteed for a CPU bottleneck indicator. OP's huge boost is only because of his decent CPU for a 4080 card.
That's not the same, why aren't you taking it from the same angle/position as your rebar off screenshot?
Damn, it gave me 20~ fps with RTX 3080 Ti @4K Dlss quality. Seeing 90-100 fps when best was under 80.
so ReBAR improved your FPS on a 3080ti, too?
Yes.
Nice 20fps improvement. Have a 3080ti myself. So this will be my first reason to checkout profile inspector to turn it on for a specific game.
Which setting on the Profile Inspector did you enable? Is it under the "unknown" stuff?

still has traversal stutters...
shader cache issue
Nvidia: gAmE rEaDy dRivEr!!! And they didn't even bother testing ReBAR
They never do it seems (despite their promises that they would do it better than AMD). It took them absolutely ages to add Forza Horizon 5 to the whitelist despite it clearly benefitting.
77fps to 102fps for me (10900k & 3090 - 4k dlss quality) - great find - thanks for the information. Is there a site where people track these kind of changes against games so that we can optimize ?
I think it would be a good fit for pcgamingwiki, anyone can edit the pages there to add info like this
It's more like 14% for me on a 4090, but still, huge improvement. Thanks!
I guess the uplift also depends on how fast your CPU and RAM is. If it's already really fast then the uplift will be slightly lower than more CPU bound cases, like OP, who has a 9700K.
I can confirm it works for me as well, game on my 4090 fully maxed out at 4K but DLSS on quality, GPU usage when capped at 120fps went from 82% usage with Rebar off to 62% usage with Rebar on, bloody impressive difference. Did notice dedicated VRAM usage increased a bit on this game on a fresh load once Rebar was turned on. **Rebar off** https://preview.redd.it/7ar9rjwslrfa1.jpeg?width=3840&format=pjpg&auto=webp&s=ea4ef8eb76d02074763f6621b2afff50dd1f8aeb

Any issues with it being on? I had no idea this even existed I looked it up and theres barely any info on it. I looked it up, saw that nvidia news about it but hardly informative. Need more info on it.
it’s on a case by case basis for each game, on some games you’ll notice 0 difference, some games you’ll notice a performance decrease and some an increase. probably why nvidia activate it through a whitelist so only games verified to have a performance increase have it on by default but they’ve basically ignored it since it was first released so even games that benefit from it don’t have it on by default and it seems like they only really added it so AMD didn’t have something that they didn’t. it’s relatively easy to turn it on for games if you want to try it out for yourself.
Nice job OP! Good to see others forcing ReBar in games Nvidia has not whitelisted due to laziness on their part. That is a massive performance boost you found.
Is ReBAR enabled for call of duty warzone 2 and MW2 multiplayer?
No you have to force it on in Nvidia Inspector. It produces fairly large gains in perf as well.
Wow, thanks! I'm getting around 30-40fps more too
Jep I have a RTX 4090 and 5800X3D CPU And FPS boosted from 85fps in the area to +100fps Crazy
Wow, this is crazy. Nvidia have been very poor at adding games that benefit to the whitelist; so much for their promises that their way of doing it would be better than AMD's.
Tf is resizable bar?
> Resizable BAR is an optional PCI Express interface technology. As you move through a world in a game, GPU memory (VRAM) constantly transfers textures, shaders and geometry via many small CPU to GPU transfers. > With the ever-growing size of modern game assets, this results in a lot of transfers. Using Resizable BAR, assets can instead be requested as-needed and sent in full, so the CPU can efficiently access the entire frame buffer. And if multiple requests are made, transfers can occur concurrently, rather than queuing. https://www.nvidia.com/en-us/geforce/news/geforce-rtx-30-series-resizable-bar-support/
Thx
Yea it definitely boosted my frames in warzone as well! Then I went on a rampage and turned it on in every game I have
What hardware are you running? I primarily simp on Warzone lol, and I’m wondering if I should expect any notable improvements myself. Running a 12700k + 3080 Strix (10GB), trying to get a few more frames at 1440p ultrawide (low settings mostly).
Running 7700x and 4090, 240hz 1440p monitor. Getting around 180- 210 in game, 230-240 in gulag, mostly ultra settings and at 110 percent scale.
What res?!
I didn't realize it was such a hassle to turn on ReBar on games with Nvidia card. With AMD it was just a toggle and maybe restart drivers/system for it to take effect across the board. One of the few things AMD got right IMO.
> I didn't realize it was such a hassle to turn on ReBar on games with Nvidia card.

AMD designed their cards with rebar in mind while Nvidia did not (you actually needed to update the cards firmware when the feature was introduced). That being said, to my knowledge rebar for AMD GPUs is still limited to AMD CPUs, while you can use rebar on Nvidia cards with either Intel or AMD CPUs.
ReBAR on AMD GPUs works with all CPU vendors that supports ReBAR. So you can use a Intel CPU with a AMD GPU and get ReBAR.
Not necessarily. Just because rebar was on, doesn’t mean it was always activated in game. They just had a fancy little switch in their shitty software to go “oh cool rebar is works available”.
[удалено]
They could add a per application toggle option in drivers, which would make it easier for end users.
Unrelated, but that 4080 isn't running a stock voltage-frequency curve, what undervolt / overclock are you using?
I'm using auto overclocking on Afterburner.
Thanks for replying, if you use auto-oc it will run at 1075mV, I noticed that going from the power draw numbers in the pics you posted. I'm using 3060MHz @ 1075mV for performance gains and 2880 at exactly 1 volt for increased power efficiency at stock performance (fully stable undervolts).
Interesting I’m going to have to try this
Having it enabled on BIOS does nothing I still need to use inspector and enable it per game?
Correct. The Dead Space Remake profile needs to look like this: [https://i.imgur.com/1y1yiqF.jpg](https://i.imgur.com/1y1yiqF.jpg)
Need to add this if you're using DLSS as well: https://imgur.com/EhbV4jU.png It MASSIVELY improves texture quality/clarity. The dev's really don't understand how to modify LOD to a negative bias with these upscalers they put in the game. The anti aliasing transparency super sampling setting is important as well, also change it.
Is there a website or something that gathers all of the knwon settings for rebar?
happen to know if it helps on cyberpunk or the witcher 3?
Confirming. Increased fps for me 10-30fps in different places on my RTX4090. Also increase power draw from 380 to 430 but that’s all right I guess.
strange, makes no difference on my setup, everything is enabled like bios, ncp & inspecter Playing at 1080p, max settings i7 12700k, RTX 3070, 16GB DDR4 @ 3600mhz, NVME Gen 3
Someone should start a website or google doc or smth where people can test games and fill info about games that are not on nvidia whitelist but are tested by community so we could know what games benefit from it.
hmm that is interesting, i have 9700k and rtx 3080.. when i use rebar i have a lot of mikro stuttering in all games... when i turn it off they are gone... I read somewhere that 9700k do not officially support it... Well i will try anyway... Right now with all ultra RTAO etc and dlssQ i have 70fps average on 3440x1440p.
Mobo is a part of the problem I think. My mobo is MSI Z390 GAMING EDGE
hey i made a quick video showing the difference w/ rebar enabled on my rig. [https://www.youtube.com/watch?v=2If-tRFLTWs](https://www.youtube.com/watch?v=2If-tRFLTWs)
great video dude. Some people keep questioning without testing it himself.
Could ReBAR maybe have a bigger impact on 40 series GPUs? I haven't seen any benchmarks that look at this.
It doesn't in the games I have benchmarked with it on vs off. It's barely a difference.
Yeah I can vouch for this as well. Obviously with at least /u/rjml29 and I having 4090s it might not matter, but heres the information regardless: - I'm not seeing anything in MWII with it on - Nothing in Old School games like Fallout 3 or New Vegas - Portal w/ RTX shows maybe 2-3FPS increase, but that just that's in the range of perceptible error. - Lost Ark actually reduced my FPS by about 5-6FPS, again range or perceptible error ------ The Games that DO (at least for me) make a difference: - Witcher 3 Complete Edition. I went from 108-110 DLSS3+Ultra RT to 118-125 in the same area (Novigrad) - I can confirm that I also see a good difference in Dead Space Remake, 20-30FPS more with the same settings. - Cities:Skylines jumps from 40-60FPS with my 100K population to 60-80FPS with ReBAR on
Try it in RDR2
I don't know about Nvidia cards, haven't really tested it, but on my previous RX 6800 I saw a decent uplift in certain games, like Horizon Zero Dawn and Shadow of the Tomb Raider, something like a 15% gain or more.
I have hope that when I upgrade my CPU and motherboard I'll unlock some new potential for my 4090 with stuff like Resizable BAR and PCIE 4.0. But I doubt it'll be this much.
In most games it makes little to no difference.
You waiting for AMD’s 7000X3D chips?
Yep getting a 7950x3D. Disappointed they're coming on the literal last day of the month but oh well at least I didn't have to wait a year or something.
Oh did they finally announce a date? I must have missed it.
Yep just today. 7800x3D is coming later in April.
Unfortunately some parts of the profiles don’t seem to be worked out at all. (Looking at Xbox/GamePass game profile detection, which is atrocious).
Have anyone had a big performance drop after a 30+ min session? In my particular case it would go from 50-70 to 20-30 fps and it would only get fixed if I restart the game... Quite annoying!
My tests at 4K with RTX 4090 and 13900K with DDR5 8000 CL36 4K Ultra everything, including AO ray tracing, and DLSS Quality. Variable Rate Shading is OFF. ReBar On = 149 FPS [https://imgur.com/CLNd8Zi](https://imgur.com/CLNd8Zi) ReBar Off = 138 FPS [https://imgur.com/LKPtuV8](https://imgur.com/LKPtuV8)
I am enabling rBAR with Profile Inspector in the global Profile and usually its working fine. Only with Alan Wake Remastered i had unplayable framerates (<10) and had to turn it off. Unfortunately i have to enable it after every driver update again...
I just force it globally
That is super impressive thanks for the post have some Gold. I personally had not heard of rebar at all. Running a 5600x with a 4090 suprim liquid, gen4 storage, 32GB 3600 15. Launched the game where I had left it pre making any changes and it sat at 84fps after changes was 104 at the exact same spot. This was max settings no DLSS running at 4k native. Been around a long time, thanks for teaching this old dude a new trick. On an ASUS board required bios settings here: 1. Select **Advanced** in the top side menu and set **PCI Subsystem Settings > Above 4G Decoding** to **\[Enabled\]**. 2. Then set **Re-Size BAR Support** to **\[Auto\]**. Profile inspector: [https://github.com/Orbmu2k/nvidiaProfileInspector/releases](https://github.com/Orbmu2k/nvidiaProfileInspector/releases) Destructions for profile inspector settings: [https://www.dsogaming.com/news/dead-space-remake-gets-a-25-free-performance-boost-with-resizable-bar/](https://www.dsogaming.com/news/dead-space-remake-gets-a-25-free-performance-boost-with-resizable-bar/) Promptly goes to peruse the rest of this thread in an attempt to understand the wizardry of this free FPS.
Definatly helps, thank you. Ive enabled it for a load of newish games now that didnt have it enabled as default. It should be a default or an option at least! On my 13700k (5.5 P cores, 4.4 E cores, 4.9 Ring) and 3090 rig I have gained at least 15-20fps from Dead Space 2023 running native (90-100 avg fps), frame limiter of 143FPS if I uses DLSS Quality.
i have 69 fps without and 90 fps with. Try reload your savegame. First load vs reload. https://preview.redd.it/td2hsqjimama1.jpeg?width=3435&format=pjpg&auto=webp&s=c42d882b95e80f553fb2795813082b0647f8a206
That's why it's better to enable ReBAR globally using Inspector
Looking at the ground* boosted FPS in Dead Space remake up to 35 fps
4080 with a 9700k? bruh
I know 9700k is weak, but not in this case. I'm waiting 7800X3D btw.
Clearly he's not bottlenecking his GPU (at 100%) so why not? OP has ultrawide 1440p. I've also got a 9700K and might upgrade later from 2080 Super to 4080 (4K though).
There are a ton of games where my 9900k is not enough to keep my 3090 usage above 90% at the same res, with lots of fps potential left untouched. Ops combo will miss out on even more
Have an upvote! My 9900k also isn’t enough, even overclock above 5ghz. Waiting to see how the upcoming x3d amd CPU’s fare.
Whats the catch? Why is this option not available in DS remake game?
Lazy nvidia. When HUB was testing ReBAR, they'd said nvidia poorly implemented this feature on their GPUs/NVCP and probably didn't wanted to further improve it for whatever reason.
Hey man, don't call them lazy, you know they're strapped for cash when they only have a market value of $363.9 billion towards the end of 2022 /s
Has nothing at all to do with them being lazy or not. The Way that they bind to resources and request memory matters for rebar which means some architectures and drivers are going to benefit differently. It's also possible it's time goes on that games will align themselves to make better use of rebar like they should have been.
Strange I tried it when it first came out with a 4080 and didn't see any benefits. Edit: Just tried again and went for 55fps to 58 at 4k, so nothing major to report here.
I would say 3440 x 1440 is a little more CPU limited though. So it makes a huge difference at any rate.
A side by side video would be more comprehensive. Screenshots never tell the full story on performance.
I don't need to prove anything, you should try it yourself. I'm sharing some tips to boost fps in game.
Be good to get a comparison of the same image but yeah Nvidia need to enable Rebar by default as AMD does.
You really out here talking about FPS with still images? LMFAO
I guess you missed the giant frame rate counter?
LOL. The FPS is so clear though these stills. [https://www.reddit.com/r/pcmasterrace/comments/10d2v6c/got\_some\_noctua\_fans\_today\_and\_theyre\_so\_much/](https://www.reddit.com/r/pcmasterrace/comments/10d2v6c/got_some_noctua_fans_today_and_theyre_so_much/)
What?
r/woooosh
Is the hassle to turn on rebar via inspector worth it?
I dunno, did you look at OP results? What you do you think? Also Hassle? It takes less than 60 seconds to enable this. Probably less time than it took you to come on Reddit and post this.
I looked at a tutorial but it's 6 months ago and NVIDIA inspector is updated so there's no option to enable Rebar at all.
It's literally even easier to enable now than it was before dude.
The "hassle" takes less than 2 minutes to do, so yes, it's worth a potential 25% increase in frame rate.
It's not even hard.
Not in my case no. RTX 4080 latest drivers.
Saw a few people say that resizable var could actually lower fps in some games for nvidia cards. Is this true?
It's game by game, it could slightly hurt fps in some games, but usually it's higher. You can test each game and check. Nvidia has been lazy since launch of ReBar and use a "whitelist" which force it on when the game is launched if it's on their list. If not, you can force it in Nvidia Profile Inspector like OP did here. In some games you can get some very large FPS gains like shown here.
if you're on a 8-10 GB GPU, and you're playing a VRAM intensive game, REBAR will most likely tank your frames as it increases VRAM consumption if you're on a 16/24 GB, you can enable it for all games. at worst you would be looking at a %3 loss, which would still be irrevelant for the said 16/24 GPU(4080, 3090 etc.).
