I’ve been playing this game nearly since launch and I’ve never had frame drop problems until about five or so months ago. It makes the game irritating to play, especially during comp. I’m sure that a patch during late last year is what caused this issue and I’ve followed this post which helped the problem very briefly before it started back up again. I’ve also reinstalled the game, which didn’t change anything. I’m still having the exact same problem. (edit)I’ve installed Geforce Experience and then uninstalled it. I’ve also uninstalled Overwatch from the launcher, then reinstalled it.
