As I’m sure you’re aware Medal of Honor: WarFighter is about to launch. AMD found an issue that came up last minute that affects this game, where you might experience an application crash if you’re using a CrossFire configuration while Deferred Anti-Aliasing is enabled. This only affects the newly released 12.11 beta 3 Catalyst.
AMD has now fixed this issue and updated Catalyst 12.11 towards Beta 4 which you can download here.
