So I've just bought Battlefield 3 and I'm having a hell of a hard time with it. No matter what settings I put the game on it stutters like mad. It will be running smooth at like 90FPS but then plummet but then go back up. It;s impossible for me to get a smooth framerate. I'm using an 4.7Ghz OC i5 with 6850s in Crossfire Using Catalyst 12.1 with CAP1 and I'm not sure if it's these drivers or some other problem such as overheating. Anyone got any experience with these drivers and crossfire so I can eliminate it as the problem?
