I'm done with CF. Going back to nVidia (8800GTS 512).
That's strange.......i also run Vista x64 and 1920x1200 and even 4xAA the game runs very smooth.Running 8.1 hotfix drivers and all updates, hotfixes plus sp1.
I also have flashed the cards with Daidalos bios to keep 2d and 3d the same speed.Maybe you should give it another try.

Good luck
