Speedruns of all categories now must be capped at 120 or lower frames per second, due to a new discovery that presented an unfair advantage to players running worse performing systems. The discovery made it so the higher your frames per second, the faster you could swim in a large body of water. The full discussion can be found in the #underworld channel in Tomb Runner. As most people were playing on a voluntary cap of 120 frames per second anyway, this probably will not affect any present runs.
