thanks for the responses, i dont have amd catalyst, theres nothing going on in the background, but now that i think about it, my pcs fans used to spool up to really high revs when i was playing a demanding game, and now they remain quiet, do you know if theres any way to test my power suppply? i went and downloaded a bunch of bench mark software and temp monitors, and neither my cpu or gpu are overheating, the cpu doesnt go above 20c even with graphics settings on ultra, when i first got this pc a year ago, i thought i remembered playing dcs on highest settings getting about 20 fps. yes my gpu has 2 gigs of memory.
