If I attempt to load or start a game after turning water reflections on the game is black screen at the point just before or at the moment you spawn. If the all other graphics settings are low enough this may not occur. Also the sound and cursor and some keys seem functional to some degree based on in game sounds if the settings are high enough to trigger the bug but not high enough to completely lock up the game.
