Well beside demanding what CryEngine3 engine does today is too much for such big world like DCS. CryEngine3 does not simulate flight, nor avionics, it is quite limited and small world in comparison. That is why in FPS games PC resources can be used somewhere else instead of true flight simulator related calculations and that is why flying usually is a hover here and there, shoot this and that arcade game ;)
Current DCS damage model delivers everything of that already. Do some crash testing with the Toad ;) Every part in DCS-level a/c is independent, there is full and part body physics, each part has own weight, independent calculations and so on... ED tell me if I am wrong.
