Could you be a bit more specific? E.g. do you mean "when the camera moves, the game runs slow -- why?" If so, TV is multi-threaded but lots of stuff must be done on Unity main thread -- mostly due to Unity design (e.g. mesh assignment and Collider generation from mesh -- a known "delayed cost" IIRC). HTH ... though I'm not sure this is your problem though since I've not seen too much of this. So, er, please clarify?
