-> There is an issue with setting higher resolution, including native when it is already lowered. Then a screen resolution can be restored to native only in the config file as the game does not show anything above the actually lowered screen resolution. It can be done via `user.cfg` which is located in the game installation directory, not in the Windows' `Documents` like mentioned elsewhere.
