A reason 'Why' Kepler needs more VRAM...as 2GB is not going to cut it for us mere mortals with ultra high res Screens!
So here's 'Some' examples of using 2.75GB of VRAM! (Not System Ram...) In Crysis 2 maxed to the hilt in DX11 and Forced in NV control Panel to use 16x AF and 16XQ CSAA @ 2560x1600. Running @ 60FPS.

    It should be noted that Crysis 2 is poorly optimized for DX11 and high res textures. However, I can run it in on Ultra (DX11 on) at 1920x1080 with 2 GTX 570's and maintain 60fps and that's with only 1.28Gb of VRAM.

    You may do. But 1920x1080 is only half the amount of pixels of 2560x1600. So this is where more VRAM is needed.
    I did a test with BF3, and noticed that you needed 500MB more VRAM to max out BF3 with 4x MSAA between the 2 resolutions.

     Need to go to Spec savers...
     
    Here's Some BF3 comparisons. Maxed out with 4x MSAA. Varying between 2.1GB and 2.4GB VRAM usage.

    I agree that modern high end GPUs need a lot of VRAM. I run 3x30" monitors in surround and 3GB is just enough in some games with 0xAA. I get about the same VRAM usage as you (slightly more) on my setup with 0xAA in Crysis 2. Skyrim (heavily modded) almost maxes the 3GB @ 8070x1600 0xAA as well. 2GB just doesn't cut it with high resolutions.

    Added BF3 Screen shot usage.
     
    willdearborn - You are just insane running 3 30" monitors. I bet it must be epic!
    I had 3 U2410 in NV Surround. But the problem I was facing, was using FOV fixes in allot of games to make them look right, and not too stretched. I soon sold them and went back to my 3008WFP. But now I'm regretting getting rid of them...(F1 2011 was Epic on them, and now I'm back to single screen, F1 2011 isn't the same...)

    Personally, I think the flagship GPU should always come with greater VRAM.

    Exactly my point!
     
    Maybe they should give us expansion slots, so we can buy and add as much VRAM as we need...

    Good thread. Love the eye candy.
     
    Pixel count is important.
     
    For those who do not think you need more than 1.25GB of Vram... That is just fine.
     
    For those who are not quite sure what the difference is in pixel count from a 1920x1080 and a 2560x1600... It is like going from 720p to 1080p. 720p is just fine and dandy. But 1080p is far more accurate with less blending and gives off a far more accurate visual effect.

    That would be awesome. I would love it if they made GDDR5 available in sticks, or really any form factor that they could fit onto a video card.

    You can get it for under $20 now.  It's a great looking game but I lost interest fast.  Gonna have to go back and give it a go one day, along with about 12 other games.

    I want to clear up a misconception that my be happening here.
     
    Just because a game is using up ~2.5GB of VRAM or whatever does NOT mean that it NEEDS 2.5GB of VRAM.  IT may very well run completely fine and at the same performance level with only 2GB.
     
    Applications are written to use more RAM when more is available for caching ahead of time whether they actually NEED it or not.
     
    You only run into a problem when an application really does NEED more RAM than you have.  However, the only way to find out if it needs that much RAM is to run the application with a limited amount of RAM and see if it runs out or affects performance.
     
    You cannot determine the minimum RAM requirements for an application with a card that has more ram than the application actually needs because the RAM usage will appear inflated to greater amounts than is actually needed.

    Yup, like trying to run a newer title in Surround with 1GB of VRAM...such as BF3..just doesn't work well.  I tried it with my 470s.

    I have used the step up program to the GTX 680's 2GB, so I will post my findings, using the same settings, when they come. (May be a few weeks).
    Then we will see if it's a case of caching the free VRAM.

    Nice screenshots! DX11 makes both my cards shoot up to 90+ degrees C. But when only running one card I get 30 fps and it doesn't exceed 70. I really think CryTek could've optimized way better but it's obvious Crysis 2 was meant for consoles.

    Thanks for all the comments!

    I want to clear up a misconception that my be happening here.

    Just because a game is using up ~2.5GB of VRAM or whatever does NOT mean that it NEEDS 2.5GB of VRAM.  IT may very well run completely fine and at the same performance level with only 2GB.

    Applications are written to use more RAM when more is available for caching ahead of time whether they actually NEED it or not.

    You only run into a problem when an application really does NEED more RAM than you have.  However, the only way to find out if it needs that much RAM is to run the application with a limited amount of RAM and see if it runs out or affects performance.

    You cannot determine the minimum RAM requirements for an application with a card that has more ram than the application actually needs because the RAM usage will appear inflated to greater amounts than is actually needed.



    I have used the step up program to the GTX 680's 2GB, so I will post my findings, using the same settings, when they come. (May be a few weeks).
    Then we will see if it's a case of caching the free VRAM.


     
    Yes I look forward to your test.
     
    I truly believe that a 2GB card will work for the settings you used above 2560x1600 16xAA, etc. which showed ~2.7GB being used and that you won't be VRAM limited on only 2 causing terrible performance.
