Hi i have an alienware m18x laptop. I have a 2820qm and dual 460m gtx's.
When i'm playing some games like diablo or black ops 2 my video card underclocks itself causing a huge fps dip for anywhere from 1-20 minutes. Fps goes from 100 down to like 10. I play on stock settings at 675mhz coreclock. but when the problem happens it goes down to 203mhz. i have no idea why it's doing this. My video card temps never go above 75C. what could be the problem? I've tried multiple drivers all with the same problem.
