I agree about the nozzle animation, but that's probably a function of the aircraft's 3D-model more than anything else. So, I wouldn't expect to see any improvement in this regard before we get new 3D-models. FWIW, I believe the nozzle animation is not sequenced properly either, it should be wide open at idle thrust and then close down progressively as you throttle up only to open fully again when you go into afterburner.
Mobius1, a video would be excellent, thanks!
