I'm not sure about the mouse. How do i check that? And I'm actually playing on a 720 tv right now but my pc is set to 1920x1080 so it will record games properly. It's a temp setup until i move at the end of summer. I don't think that would affect anything though, would it?
Some mice let you control their Sensitivity outside of the games you play. We actually upped the games sensitivity scale a couple days ago when I noticed it was super low for me (I pay on a pretty low sens 800dpi), but fine for my teammates. But it’s clearly still way too low for some users. Don’t think the tv would be the issue, just trying to rule things out. Thanks for helping us learn and improve:)
