Another regression for me. Both Left4Dead 2 and Serious Sam 3 are back to running like shit with this new Catalyst 3.11 Beta 9.5 driver. (I played both just last night and thought to myself that I was content now) If both of those have been degraded, then probably ALL my games will hurt. I can't even be arsed. Those are games that modern hardware doesn't even slow down for in Windows. (I'm not even that modern... Radeon HD 5870 on a Core i7 3.2 GHz system, and both of those games are trivial)
