Hi I have a HD 3850 video card which I use to play cod4. I get 80~60 fps before but when I cleaned my pc and applied a new coat of thermal paste to my cpu (the cpu is getting hot lately) I now only get 40~~20 fps. Please help I downloaded new drivers for the card ,I even overclocked the cpu and gpu ( I have amd 5600 x2 @2900 overclocked to 3200). Please help I can't enjoy my gaming when I have such low fps. Thank you.
