Overwatch aim feeling weird

I just came back to Overwatch after playing Fortnite for a while and my aim feels weird. I tried using the equivalent sens using the sensitivity matcher tool (simulates the same mouse movement in both games and I adjust the Overwatch settings until I get a 360° turn just like in Fortnite) and I set the FOV to 80 (just like Fortnite as far as I know).

It still feels pretty different. For some reason Overwatch feels more ‘fluent’ even though I’m roughly on the same FPS. It also seems like my sens is higher in Overwatch even though the sensitivity matcher tool should make sure it’s exactly the same.

Does anyone have an idea where this feeling comes from and if there’s actually still a difference? My best guess is that Overwatch has a different vertical sens but the same horizontal sens (the sens matcher only helps comparing horizontal movement).

Set fov to at least 100-103, your camera will stop acting like landscape panorama view.
Moving from 3rd person camera shooter to 1st person may cause this weird feelings

I’ll try, thanks. Others also reported that fullscreen would feel better than windowed fullscreen, but that seems to cause screen tearing for me on 144 FPS. Is that a known issue with a fix?
