Wondering if anyone else has noticed poor performance with the past 4 months worth of AMD Catalyst drivers in SL? Up till and including 11.7 everything is fine. Nice fluid movement, decent framerates. If I install 11.8/9/10/11 the performance goes to pieces. Stuttering, 1-4FPS, screen locks etc. If I roll back to 11.7 it all works fine again. Even adjusting the graphics settings to minimal does nothing. I have just rebuilt my main PC as a part of this but have only installed 11.7 on as I was none to happy to install 11.11 etc. Am I alone in this?
