So i like playing my games in fullscreen windowed but according to my EVGA precision when i run D3 that way my GPU sits at 99% and the temp topped at about 63 Celsius.

After toying around i found only fullscreen non windowed in a lower res (1600x900 wide) on my 1920x1080, making it look a little grainy and stretched. But it still sits at 50-54% usage, while i run WoW on max res high settings and it gets to 25-30%.

Any suggestions on what i can do to fix this?

If you need any info on my PC ask me for it.
