So I've had this problem for a while now were when I play BF3 after say 10 minutes my GPU usage drops low making my game have extreme lag. It also happens in other games such as Skyrim and Dead Rising 2. My computer is fine at running the games, I get about 60 - 80 FPS on Ultra while playing BF3 but I don't understand why this happens. My temperatures are fine from what I know, my GPU is on 40C and my CPU's on about 45C. I think it may be a PSU problem as from what I've heard my PSU isn't a very good make (HEC Compucase G7 Power Extreme 880W Power Supply) It may be that it's overheating and resulting in not being able to put out the wattage for my Graphics Card, if anyone knows any software where I can monitor my PSU I'll give it a shot.
This is a screen shot of my results on MSI Afterburner displaying my GPU Usage from idle to make use (Playing BF3) These 50% drops in GPU Usage cause major FPS drop dropping it down to about 20FPS.
