I'm having somewhat the same issue. I can get as far as the 'class selection screen' (Machine gunner, Marksman etc.) and the game will literally stop there. Sometimes it stays frozen for up to 5 minutes. Granted it doesn't actually crash but its definitely enough that I have to Ctrl, Alt, Delete to get out of it at times. Sometimes it works fine then other times it freezes and goes no further.

Yeah had this a few days ago, raised weapon to fire at an opfor only to literally run into him. Needless to say I died not because of my mistake. Couldn't do anything to stop moving, couldn't fire, infact as wallaberto states all my controls on keyboard locked up. The only way I could fix the issue was to Abort the game.

Not third person view affiliated. Our server has third person view locked out so you can't actually use it.

Yeah in the BluFor vehicles they look like they're in the old 'brace for impact' position with their heads between their legs. This happens for the two passengers in the back and the passenger in the front.
