I have read topics on other sites of people able to run Crysis Warhead on systems very similar to mine on Gamer settings with upwards of 25+ fps. With the CCC graphics config they get 45+ frames. I have tried running the game on Gamer without the tweak, and get around 15 fps. With the tweak I get bumped up to around 20-25 fps. This is on a fresh install of Windows, and all drivers are up to date. Any suggestions or ideas, or what fps you get with your system?
