I've been having this very odd issue with my games lately. When I first turn my computer on and boot up a game, the framerate will be perfectly fine and the game will run smoothly. If I quit the game and open another game my framerate plummets. The issue will keep happening until I restart my computer. I've done scans with Malwarebytes, Avast, and SpyBot but they come up with nothing, and all my drivers are updated.
It's getting really annoying having to restart the computer every time I want to play a different game or re-open one. Hoping anyone can help me get this sorted out.
