Btw it says that FOV is not possible to change (locked), but you can change it by mouse-scrolling in-game to zoom in and out!
Mouse sens config is in
Steam > userdata > your user ID > 632360 > remote > UserProfiles
and can be adjusted accurately under
<mouseLookSensitivity>0.01000000</mouseLookSensitivity>
