First person camera moves far more when rotating than vanilla
The first person camera will sway very slightly while the player character idles. This does not happen in vanilla. togglecollisionboxes makes this more obvious.
When you look straight down and turn in Vanilla, it's centered on your position. In OpenMW, it orbits the center of the player's position, with a forwards offset.
This probably effects what can be reached from the player's position in some situations.
