When I tried to profile it, everything went too fast. Previously, going from PRB to PTO was several minutes, after I enabled profiling in firefox, it took several seconds (first 2 times I've crashed, because it was too fast for me). It was fast up to end, but when I was near PTO and about to land, everything slowed down and I had consistent 830ms per frame. I'll try to check later when I'm back from work.

Meh, now it works too fast, almost unplayable, I can't even steer properly, one keypress and speed is already +4. I believe it's after some change in code.
