I've been experiencing really terrible performance on Battlefield 3 and Diablo III recently, everything's on the lowest settings and I still get awful fps, sometimes in the 8-10 range. I've completely reinstalled windows 7 and have reduced all the OS' to maximize performance, updated all the drivers. 8 GB of DDR3. My processor's an I5-660 and my card is a GTX 550ti. Any recommendations would be grealty appreciated.
Drivers are all updated. My network's a home network with a linksys WRT110. Only computer connected to it is my own, occasionally an ipod touch or my girlfriend's cell phone. Also I ran 3d mark and all my scores, except for graphics, were way below what is expected for my hardware. Graphics were 2300+, physics was in the 1100 and the combined was barely above a thousand.
Looks like it is heat. CPU's running 65 C idle and over 100 when playing a game. Can't believe I didn't think to check myself. The CPU fan seems to be running fine. Should I try reapplying thermal paste or do I need an aftermarket heat sink? Thanks for all the help.
