I recently began streaming and I wanted to stream the games that I play the most. These being Hearthstone, Starcraft 2, and League (sometimes). I ran into an oddity while play starcraft 2. my mouse is super choppy to the point where gameplay is impossible. I've ran a lot of tests but what I've found, this only happens when I have OBS open. Note: Not streaming or recording, just open. The issue goes away when I close the window. What is going on that's causing this and how can I fix it?
