Just Downloaded & tested newest AMD drivers for my 6950 card , Its been a while since i checked but I just cycled through most of the maps (Vsync is ON ) & Im getting a pretty solid 60 fps on a mix of med/high settings , i didnt see anything outstanding in the release notes but it seems to run with higher fps now ,....Im not seeing those wild dips into the 40's anymore yet , so you may want to update & see.
