Do not install latest drivers which came out yesterday (version 11.11)!! Before driver update I had average 45 fps, after driver update it dropped to 25-30 average and it isn't really playable. Darn... when will AMD release some decent drivers for single / crossfire gfx. I use Radeon 4890 btw. I was hoping that I will get more fps with those drivers but that proved to be wrong.
