For some players, the game stutters if you move your mouse too quickly and it can very easily cause you to get turned around and lost if you're running fast. Additionally, the mouse can feel like its speed is limited, almost as if it thinks you're using a controller thumbstick instead.

For me, the file was completely empty to start with so it now looks like this.
