Ok so my rig is an amd fx 4.3 turbocharged 8 core cpu with slied nvidea gforce 2gb ddr5 gtx 660s with 750 watt power supply and 16 gbs ddr3 ram ect. Ok so my problem is.. Games like watchdogs i can play ultra without any problems averaging 50-60 fps but sometimes when i start up the game ill get good fps but when i move the camera around it wants to hesitate and every few seconds it jerks ect. I have used geforce experience i have all my drivers up to date and using optimal settings(which is max) so the game does this usually until i have been playing a little while and seems to smooth out.. I mean sometimes i start the game and its almost perfectly smooth and other times its hesitant and kinda jerky.. All on the same setting? Any ideas??
