Hey TimmyO123,
It looks like you’re using an RTX 2060 card. There are some issues between RTX cards and Overwatch that our dev/QA teams are investigating, so your issues may likely be related to that.
I would recommend trying this workaround which involves renaming the Overwatch.exe and using that to launch the game, to see if that helps for now.
If that doesn’t work you may also want to try just lowering the graphics settings in-game, and disabling background processes just to test those as well if they haven’t already been tried.
