Do you know how I can get rid of the random stuttering and lag? I know my cards are capable of running it because at some points it will shoot up to 30-40 fps for a good 10 or so seconds.

Textures are getting swapped into and out of memory, but your cards don't have enough of it. SO when you move around too much you get stuck in a constant memory swap state. Conversely if you stay put in a room, a box, you won't be swapping textures and speed goes back up cuz everything fits in the little buffer that you have. Go outside in that lush vegetation and you are screwed. That's why it is seemingly random to you, but it is is not by accident. Ppl with 58xx cards figured this out last year, which is why 69xx cards have double the memory.

If you look at the video in the OP, it is pretty much random because it will go up to 30-40 fps while I'm outside, looking at the "lush vegetation"

And also as stated earlier in this thread the same thing occurs at 1920x1080 so it is not a vram issue

hate to say it again... but it is a Vram issue. Your trying to push way too much out of those cards with the settings your at. Your stuck in a constant memory swap loop... its why its cycling this stutter on you. It catches up, then loses ground.. rinse and repeat.... your gonna have to lower settings.


Why the need for 12Gb of ram on your MB ? your working the IMC on the chip to death. You would notice a great performance gain if you cut that in half.

It's not a vram issue. How many times do I need to say that. It happens at 5670x1080, it happens at 1920x1080, it happens at 640x480.

If I load the island level in Sandbox 2, I get a very consistent (note that i'm only aiming for consistency, not high fps) 25 fps with no lag and stutter when I preview the level. Only when I actually go in game it beings to stutter. It's the same level, same textures, same rendering, except one is in the editor and one is in the game.

You shoulda mentioned the other info, esp the sandbox. You might have a corrupted crysis user folder, delete "my documents/mygames/crysis" then start the game. Save any screens or savegames, if you have em.

Ok well now it runs better in a single card configuration.

At the same settings (5670x1080) with crossfire DISABLED i get a consistent 20 fps with no random stutter. With crossfire ENABLED it will go to 30-40 and stutter and lag at less than 5 fps.

I've also noticed a pattern,

For the first 30 seconds after loading the level, I get a pretty consistent fps between 20-40. Only after 30 seconds the random stuttering begins to occur.

(This is in crossfire mode)
(When CF is disabled I get 20 fps all the time, no random stutter)

Why don't you try single monitor mode?
