Whenever I start Overwatch, the frames are a literal slideshow for 3-5 minutes. This has only begun happening recently (past month or so), and it happens every time I open the game. If I open the game, wait for it to run properly, and then restart the game, it will begin stuttering again. I should have no problems running this game, so I suspect it is some sort of compatibility issue. I have updated my drivers and I have tried lowering game settings, neither of which solved the issue.
