For reference, looking straight up at the sky, framerate is ~300. In or near clouds, framerate is 80-120ish depending how close I am. Actually going through them it's around 80.
A behavior issue I've noticed, the only way to join a mission in progress is to exit and reenter the arena. Trying to join a mission in progress through "Populate Mission" gives a rtn -6, flightindex -1 error. Once I've gotten that error, I cannot move fields, cannot access the hangar/Oclub and so forth.
If I am in tower, if I turn my head with TrackIR, there seems to be a series of straight, bright lines moving across the ground as I turn my head. They look like they might be reflection related.
