Some ppl might remember me raging a month or so ago about my brand new ATI5750 which lagged ET like hell, while all other games seemed to run fine.
At last I have found the reason for this behavious:
ATI powerplay. New ati cards try to reduce powerusage by clocking back the gpu when it thinks you dont need it. For me this meant my 700mhz vid card decided ET didnt need more then 150mhz. Till there was an airstrike. Or you looked at goldrush bridge :') Result = FPS dropping from 125 => 80 / 50 ish.
Anyway, there's plenty of things written on how to disable it, just look for ATI powerplay. You can check wether you ATI card is scaling back closing all applications and opening catalyst. At overdrive you can see your current gpu clock speed.
If you want to disable powerplay this link can be usefull:
