This probably doesn't have anything to do with Win 10, but there doesn't seem to be a thread where you could ask for help with a technical issue, so I'm dumping it here.
This just started happening recently. I'll be playing and everything's fine, and then my FPS will drop to 45-50 for a while, before eventually returning to normal. It could just be my computer being bad but I'm not seeing anything notable in the task manager, and if I turn off the frame limit I can still get 200+ FPS... Any guesses as to what's happening? (There was a major win 10 update recently, I returned to school so I needed to install some programs, and also I broke my USB headset so now I'm going without.)
