Tried this?
QUOTE
Alright, this may come as a surprise, but Crysis Warhead is set to use 256mb of Vram!!!!!! WTF was Crytek thinking!? I noticed this while I was doing performance checks and while my system ram usage and cpu usage was fine, I noticed my GPU being under utilized. So I went to tweakguides.com and looked through the various cvars trying to find anything noteworthy in regards to gpu's.


con_restricted=0
sys_budget_videomem = 512
r_TexturesStreaming=0



I made an autoexec.cfg with that and now I can run at 1440x900 and get as high as 60fps and never, ever go below 30fps on all gamer settings. Micro-stuttering (stuttering when turning) is virtually gone and the game is just running smooth as butter

Also, r_TexturesStreaming=0 removes that annoying texture streaming issue so all textures are displayed all the time and it makes the game look quite a bit better too boot since it's not rendering texture lod at various distances anymore. You'll notice the biggest difference in far away mountains, hills and other objects..

Crossfire X i think, coz hybrid is mean for 780g mainboard, if refer to amd, previous 3870x2 also can crossfire x with single 3870, may be for 4870x2 currently not officially support by amd driver yet

as i know is 2x 4870x2 call CrossfireX.

but for this setup 4870x2 + 4870 you will get lower performance, because of memory size.
