I have had stuttering in games for a while. I think it started when I installed my new sshd, but everything seems fine with it. I tried reinstalling things directly to the drive rather than moving it there, didn't help. It also doesn't matter how demanding the game is. I play apex which takes all of my resources, overwatch which also takes all of my resources, but I recently tried star bound which takes like nothing still stuttering. Finally, my fps on overlays stays the same (in game at least).
