I have nvidia geforce gtx 560 2gb DDR5.My GPU is not performing as it was in the past.For an example dishonored was easy to run but now it run at 3fps average.

It all starts when I downloaded windows 10 and installed new driver.

Note: when I even get to main menu in the game my GPU usage jumps to 100%.

Can someone help.
I'm not that good at computer things
