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

Hey Ibrin is it possible for you to do a Crysis Bench? Or just let me know if its possible.

That would be the main deal breaker for me doing 5x1, if its not supported or i need to invest a ton on GPU power to do it lol.

Is that supposed to be 1920x1280 or 1920x1080 in the table? Seems like a typo.

Anyway, I really love that table. % improvement vs.... No, seriously it's great. That's all that I care about anyway, and you saved me the time of having to do the math in my head by looking at the raw FPS Numbers.

Sorry for the delay. Glad you like the table. Fixed the typos.

I have never had the "micro-stutter" that people reference in any of my 2-GPU CFX setups. I had it when I tried Tri-Fire with the Radeon HD 5970 + a Radeon HD 5850. So, I know what it looks like.

Which video do you see that shows the micro-stutter? Any game with a variation in fps will show some stuttering, but that is completely different that the micro-stutter.

All that being said, I don't get any micro-stuttering with the HD 6990.

Is there any sort of canned demo or benchmark for Crysis?

Did you ever run the Nvidia GTX 460 2GB card against DX11 games like F1 2010 like you went back to do with the 69xx cards from AMD? The cards are priced about the same on Newegg right now.

I'm curious how GTX 460 2GB vs Radeon 6950 2GB rate against each other in 1080p Widescreen then in Surround vs Eyefinity. In particular F1 2010. I realized the GTX 460 2GB requires 2 cards to work in Surround but still curious how it rates in Surround vs 6950 single card Eyefinity and 6950 Crossfire Eyefinity.

Well nVidia hasn't decided to send WSGF any samples... so... that would be a no.

There is this review on the Wiki so I would assume if the person still has the 2 - GTX 460 2GB cards they could run the DX11 suite to see how it compares to the 6950 #'s even though the 2 setups in the reviews were slightly different. But I think it would be interesting nonetheless.

The NVIDIA cards are owned by Paradigm Shifter. We are working for him to rebenchmark the cars with the same games at the same settings. He also has a Core i7-920 at stock speeds, so it will be comparable.
