Just learned this by downloading the MSI software. Windows was telling me low %'s but im between 88-99 on the software. It seems to be running good now. If i got into the Geforce software and put power management as high performace, the GPU runs a lower %. If i put it to normal it runs higher and better. My temp was between 60-64 in the heaviest flights with the side cover off; about 73 with it on.
I just did one of the longest flights i have ever done with no issues, skips, or anything. It ran very well. The only thing ive done now is put the texture filtering to high (in geforce software), the virtual ram "upgrade", and put my CPU to high priority. I was actually surprised because im flying on ultra and its smooth as silk all of a sudden.
