I updated my computer's windows to the newest update (feature update) and then my GPU wasnt detected at all. I tried everything like reinstalling the drivers and checking the device manager and my gpu didnt show up or work at all. When i tried opening csgo it said it was using microsoft basic render. My friend suggested i revert updates so i did. I reverted the update then the gpu was detected. So now the problem is that my gpu is severely underperforming in all games. Fps benchmarked on csgo before this was 190 and now with all the same settings and stuff its at 130. anyone got any solutions? My pc is a alienware alpha r2 with a gtx 960 i7 6700t
