So I've been looking around on the forums here trying to find if anyone else has had the same issue as me, but no luck. I have everything hooked up just fine and when I run preview stream it pulls up my game screen, so there are no issues with getting the shuttle to work. It's just that the screen flickers every 15 seconds or so. I don't think it's a problem with the computer, is probably just my drivers or my settings being funky somewhere cause it ONLY happens when I try to run it through OBS. When I have the game pulled up on the black magic express software there's never any flickering.
