Recently, something cause a drop in FPS in games like Dota 2 and Overwatch, from around 60~70 FPS to around 20~30 FPS. This happens awhile and it goes back to normal, but happens again later during the game. I also notice that the CPU for the game drops as well.
I'm not sure what was causing the problem, the graphic card or other things?
