Installed windows 10 pro x64 build 10240 a week ago. Did a clean install. Suddenly i started experiencing fps drops in every game. Like i play Cod Advanced warfare with maxed out settings. I used to get a constant 60 fps in windows 8.1 and earlier but since i have installed win 10 it only gives 30 to 60. It keeps stuttering. I switched of vsync and it got a little better. Lowered down the graphics settings in game to the lowest but kept v sync on and the problem persists. I guess its all because of vsync but i dont want to switch it off. I have the latest nvidia drivers. Didnt download any updates from windows updates. Is there any fix for this...??? Please help Dont want to downgrade back to win 8. Thank you.
