I'm also 100% certain that you will hit the VRAM wall at that resolution, I max out my memory at 1080p on Crysis 2 with the High-Res pack and DX11 patches.
There is a post here somewhere by RagingCain that explains that this is not the case.
I can't remember the specifics, but essentially he was explaining with a lot better clarity than I am now, that the game isn't really hitting a VRam limit, but is just scaling memory, so it looks as if it's always maxed.
If you're getting good framerates most of the time at the resolution you're worried about, then you're probably not hitting a VRam wall.
But what about micro stuttering? Once might ask, in regards to the VRam wall..
Check your HD, I say. Unless you're running an SSD or a Velociraptor, often that micro stuttering is your HD not being fast enough (even at 7200rpm) to keep up with the cards/games and one sees jitters or frame rate stutters as the HD slows down the game to feed it bits of info.
But SMO, maybe in your case, you are hitting the wall running two XL2410T (so Jedi!)
Yet, if running one monitor, even an IPS at 2560x1600, I'd be surprised if walls were being hit especially with Quad SLI.
But I'll be the first to admit, I'm a gamer first and not a programmer or Hardware specialist, so I could be wrong on all of this.
I'm sure RagingCain can clarify when he pops on here.
Personally, I don't think one, or even two 590's is going to hit the same limitations that people were complaining about last May with the 280.19 driver.
But maybe I'm just being biased? Because unlike a few, I freaking love my cards. I don't overclock them, I just game, game, game. Often at 120-200fps+ no matter the game.
If you're an overclocker or system pusher 'only' then I can see why one may have problems with these cards. But if you bought them solely to play games, and think you're still going to have issues, then let me send you to rehab. Because that is some serious crack you're smoking.
For me, these cards just keep getting better and better Edited by Shinobi Jedi - 8/16/11 at 11:48am
