It runs ok on my system.

In high quality, 4aa 8af 1280 I get some drops in the mid to low 30's especially on servers with 30+ players. Occasionally, will see some sub 20fps in a massive firefight..
I was expecting better performance and am not ready to lower my AA settings since this is a a game that almost requires good AA. I am running the latest beta drivers, 66.81 which are kinda buggy. Will revert back to the 65.xx series to see if it improves performance and will use the driver optimizations later tonight...
