For whatever reason outside of maps with the 2D TypeOfLevel header, the player runs faster in 2D mode sections, past their normalspeed limit, even. This only applies on the ground, and is quite easy to notice with momentum mods, as they raise normalspeed if the player is moving faster than normal.
First attachment is showing the difference in speeds outside and inside 2D Mode both on ground and in the air, while the second attachment shows how the higher speed interacts with CrossMomentum.
