I had put mine down to sensitivity 1 because otherwise it moved too fast. But then I was getting a lot of crashes so I went to windowed mode where the camera scroll is not available. And it wasn't so bad without it.

Moving seems easier without it, as does going up and down stairs, but I miss being able to turn 360 degrees to take in the view, so to speak.

This is my first playthrough so I'm wondering what is better/less annoying in the long run. Do you use it for your game?
