I have always run amd as my driver and I had to update it to play some next gen games such as Fallout 4 and Black ops 3. I used a graphics driver uninstaller to do a fresh install and I got 15.7. It said that everything installed correctly but now when ever I launch a game it either doesn't work or there is so much lag I can't even start them. I have no idea what to do. I've tried to uninstall and install again and even a system restore but the restore failed! I have and amd r9 200 sires card and 8 gigs of ram. Any suggestions?
