As I promised before, I tested the game on other computers. The bugs were enormously less. I came up with the conclusion, that most of them are caused because of my LAPTOP AMD processor (details about it in the first post), while the others computers were with INTELs. The point, where the shooting animation is about to start, is the critical one, no matter in campaign or multiplayer. The hitbox hit detection code need to be fixed (concretely I'm with : Win XP Pro SP3; AMD Turion x2 ~2GHz; AMD Processor Driver Version 1.3.2.0). I think, it's that, because the game crash/lag/whatever at this point, if my line of shooting don't have an enemy or the enemy is dead the crash/lags is gone. This is my opinion, I'm open for private beta testing.
