     * @reason This method is static, and there is a terrible UX issue if raw input is turned on at the same time as
     * eye tracking. Raw input only tracks literal mice and not other devices, leading to the game appearing to be
     * unresponsive and the player not understanding why. This overwrite preserves the user's mouse preferences,
     * while not interfering with eye tracking, and the two modes can be switched between during a play session.
