I've started recently having issues with stuttering that lasts about 2-4 seconds. It happens rarely out of games, but inside games it does it pretty regularly. I have no idea why, but my GPU get max'd out in every game. DOOM, World of Tanks, and Prison Architect. Three games of varying difficulty for a PC, especially Prison Architect, which pins my GPU at 95%+ usage. This is my PC build right now.
