That's why I'm asking. And I can't understand why reviewer ignored this stuttering moment. Even on his Youtube videos with older ATI card there is clearly visible stutter. I'm better to play with 1 card and 40 fps instead of Crossfire+eyefinity and choppy 80+ fps
So, I don't see any good reason to buy 6990 for eyefinity.
I'm thinking it's a driver issue. I just finished trying Crysis 2 out (with some minor tweaks through the Radeon Pro software) and it became fully playable with Extreme setting at 5040x1050
Strangely enough, 5760x1200 gives me pretty low frame rate. But none the less, the game is quite playable.
Now, let's take an older game like Elder Scrolls 4: Oblivion. At 5760x1200 with max graphics it runs like butter if you happen to start the game in a town. But once you step into the open world, slide show mode activates. Even though the FPS counter on fraps will tell me 50-60 FPS, it feels like 1-5 FPS! Complete ludicrous.
I believe Crysis 2 was probably heavily developed around the 6990 and the GTX 580/590. Which is why it is the best running game on my system. Really really strange. Not to mention that Oblivion and Dragon Age 2 have much older engines that take less power to run. And not only that, I don't think too many people have bought the 6990 for Eyefinity. Most forums will have threads about how they just purchased this card, and how "great!" it's running. Well, I don't know if they have compared the performance on a singe monitor with their old card, much less Eyefinity...
I'm really really hoping that AMD comes out with a nice driver fix, very very soon. A $700 12 inch brick in my system isn't what I had in mind when I dished the money out.
Anyway...2cents from an obscure end user...
EDIT: After doing some testing, it looks like all my games are fine on 5040x1050. Although Crysis 1, Warhead, and 2 will give off occasional seconds of Micro-stuttering. Although a very kind forum user just messaged me with some info to get Crysis 2 working better (will look into it later). None the less, the strange continues... :nudgenudge
EDIT 2: Sold the video card. Newegg does not honor a refund, so I have sold it and have two GTX 570's on the way. I should have went with Nvidia for dual GPU solutions long ago. :rockout
