If a player is recording a demo under Vanilla Doom, the resolution with which they can turn the player is decreased. This is due to a limit in the Doom demo format. Internally Doom uses a 16-bit integer (two bytes) to store the turning movement. When playing network games, two bytes are transmitted, for example. However, the demo format uses a single byte to record the turning movement of the player. Because of this, the range of values that a player can turn each tic is substantially reduced.
