My GTX 1070 was working fine and then the next day I downloaded the 398.11 driver update on Geforce experience. After the installation I restarted my PC and when running Overwatch I would get 15 fps on ultra setting and my GPU was at 100% even when I closed games. I rolled back the drivers but the same problem happened.
