Resizable BAR. What is it?

Games supported, had the list been updated for more than 17 games?

Screenshot-20211107-142439-Chrome.jpg
 
here's the list from nv inspector. resizable bar on nvidia is a huge hoax with no credible support on many AAA games since the feature was released

0x00000001 (Battlefield V, Assassin's Creed Valhalla, Metro: Exodus, Hitman 2, Hitman 3, F1 2020 - DX12, Horizon Zero Dawn Complete Edition, Godfall, Watch Dogs: Legion, Borderlands 3, Control, Forza Horizon 4, Deathloop, Gears of War 5, Red Dead Redemption 2, Cyberpunk 2077, Death Stranding,
DiRT 5, Metro Exodus Enhanced Edition)

they added far cry 6 then removed it since it increases VRAM consumption, they thought it'd help texture loading issues. it kinda helps but it only makes the issue appear a bit further down the line. it is practically abandon ware. i wouldn't even chase after it, since it increases vram consumption, so it will be more harmful than beneficiary once games start to pressure the VRAM limited cards even further (i made my own research, and even conducted my own tests with the 3060ti. it increases vram consumption by 300 to 1000 mb depending on the title. i can reproduce increased 500-900 mb vram usage on Valhalla).

no point in performance increase if it increases vram consumption to a point where GPU drops frames and causes lower %1 lows (which is not the case with cards with ample vram, which is also not the case in ac valhalla. but with it off, game uses 5.5 gb vram and with it on, game uses 6.5 gb vram. so its free performance boost, but once the card is full at 7.3-7.4 gb, then imagine the affect rbar would have on performance)

it will be mostly harmful for 8 gb cards if youre maxing out. it will also be harmful for 10 gb 3080 once you max that out. this feature will probably be more useful for nextgen GPUs with ample vram to consider

Load of nonsense.

That may be your experience but don't speak as if it is going to be the same for everyone else as it simply isn't for the majority of users.

Plenty of videos/testing out there showing you can and will get a good performance boost:






In my experience, it made cyberpunk, rdr 2 etc. considerably smoother (on both a ryzen 2600 and 5600x) and they were both at the brink of 10GB, this is at both 3440x1440 and 4k.

Might be worth reading up on what SAM/resize bar do too.
 
none of the videos you shared have 8 gb maxing out on the GPUs, when I specifically said that no such issues happen as of TODAY even with 8 gb GPUs. none of the games that have RBAR support can truly create pressure on 8-10 GB VRAM GPUs, since they are designed to work optimally on such cards. i talked about future ramifications, which none of your videos prove.

and your experience, i simply don't care in terms of CP2077 or RDR 2, which are lastgen games. i specifically asked you to disable rbar to test out fc6 with ultra textures yet you ponied out. your venerable Nvidia did disable REBAR for FC6 instead of you with driver update, so you're covered by the Jensen magic, fam.

unless you prove that you have better %1 lows with rbar enabled in fc6 with ultra textures at 4k with a 3080, don't bother giving any replies. i stated what must be done, if you don't have the guts for it, scram.

Your post heavily indicates that "resize bar" is a waste of time with lack of supported titles and shouldn't be pursued just because you see higher vram usage despite "proof" showing otherwise.....

Again, the whole point of resize bar/SAM is to allow direct access and remove the temporary 256mb buffer/swap system.... If a game uses more vram, it does not necessarily mean performance will be hit hard.... Again, see HZD, res village etc. etc. etc. for proof of games that will eat up vram "if they can" with no performance benefit.

As for FC 6, as per your own words, it was disabled by nvidia so no need for me to disable it and guess what, it made zero difference even when they did disable it, heck I didn't even get much, if any performance loss that some others reported, at least nothing noticeable.

There is also plenty of footage on youtube showing gpus with 8GB vram getting a benefit despite using 7+GB VRAM, I also tested it on my vega 56 and it worked wonders too despite vram usage being close to 8GB.

Again, read on what resize bar does:

https://www.trustedreviews.com/news/what-is-resizable-bar-4150689

How does this work? It essentially makes the relationship between the CPU and GPU more efficient by removing the 256MB block read limit. With this cap removed, your system will be able to handle multiple video memory requests simultaneously and prevent a queue from forming.

Since there are plenty of posts/comparisons showing the benefits of it, I don't have anything to prove nor need to prove since the comparisons are out there, since you are making these claims, then the onus is on you to provide said proof/comparisons of all these supposed issues but like most people on here, you won't provide anything worthy, until then your points are completely pointless and invalid and no one will take them seriously unless you post something to back up such claims.

And given nvidia haven't enabled it for a lot of games, where vram is a complete non-issue in the first place, just maybe, there is another reason as to why they don't enable it universally.... Not to mention, if it increases vram usage etc. etc. and benefits cards with more vram then why doesn't a 3090 see a much bigger benefit?

Got no respect for nvidia, amd, intel or any company, I just can't stand people talking complete and utter **** that they know nothing about.

So, your own research doesn't seem to have gone far enough to back up a point you are imagining might happen ?

Yes, it looks like it increases VRAM usage ... but until it really hits the limits we dont seem to really know yet. And only then will games adapt to manage it. I dont see it as vapourware, I just see it at the moment as a technology which is only now beginning to find its need.

Am I surprised that it uses more VRAM ? No, because you are allowing larger amount of VRAM access which in a single go, it'll likely mean that the unit sizes of data you can write when addressing a larger amount of memory might increase.

As an illustrative example - original 256Mb aperture size might be split into 256 x 1Mb chunks . To use a resized aperture of 512Mb, that might get split into 256 x 2MB chunks in order to achieve. So some of those 2Mb chunks might not be fully filled with data, but would appear as being filled / utilised as a result of the resized aperture.

*** I tried to read up on whether this is case with ResizeBAR, but couldn't easily find exactly how it works. I know its the case with large capacity hard drives and things. ( i.e. a 1kb text file stored on a drive which has a storage unit size of 32kb will mean that 1kb file will be viewed as occupying the full 32kb space. )
