Well, an increase from (60 to 70) fps to (85 to 87) fps is nothing to complain about. It was obviously completely playable when it was managing "a bit over 30" since it was designed that way, but I've no problem with more.

Apparently they have fixed the "vertex explosion" bug as well, where your face would occasionally turn into a mass of spikes that obscured what you were doing so much it was unplayable - needed a quit out and restart, and was the major interruption to the game.
