I know this post is redundant at this point and is pretty much a necro post. I am new to Arma 3 as I have recently became a PC gamer.
This fatigue/weapon sway system still needs work. We take the roll of a trained soldier who has vast experience with dealing with fatigue and have trained with their weapon systems.
The amount of weapon sway is absolutely over exaggerated and needs to be toned down. I understand after a full sprint you are going to be breathing heavy and your aim may be stressed, but not to the point you have it.
Soldiers train stress drills for this reason. I understand some weapon sway while shooting off hand, but not as much as you have in game. This trained soldier cant barely climb an incline without running out of "stamina".
I only ask you portray the fatigue and weapon handling of this trained and seasoned soldier as realistic as possible.
