Hello, I have a i7 4790k and gtx 970 msi... The only game I play is starcraft brood war and I never had any problems with fps ever dropping under 300 while playing that game for years but just not to long ago about 3-4 weeks ago when I first start up my computer my fps are good even after 2-3 hours of playing starcraft bw my fps are consistent 300 but after some hours or playing they drop under 200 and every click I make or movement with mouse it keeps dropping under 200 and the game gets slightly laggy I tried everything gpu update and many other things but nothings fixed it the only way I can fix the problem once It drops under 200 is restart the computer. Sometime it drops under 100 fps as well after several hours of computer being on. Please if someone can help me =(
