Hmm. Interesting. It works fine for me in the game. The quicker the shot, the less sway. If you're tired, your gun wavers. The longer you hold your weapon up, the more it wavers. Just as it does on the range or in the battle field. Especially with the heavier Mosins and KAR's. I will concede that it is aggravating at those times that we don't have more control over the sway, but still it is not an unrealistic feature. But by resting a bit (catching one's breath) and/or lowering the weapon the sway returns to being minimal.
In RO does your weapon sway constantly? Even when you lower your weapon and raise it again?
And a gun is
never still when shot from an unsupported position. One typically fires the weapon as it moves across the bullseye. That function is not unrealistic by any means. Typically, what is unrealistic is the whole breathing thing. While it is an attempt at portraying a trained rifleman controlling his breath, imo that is something that is NOT done very well in most games. If I've just run 50m and stop to shoot at a target, I'm not going to be able to magically control my breath and heart rate just because I've willed it so (simulated by pressing some button on a keyboard/keypad).
I really abhor the whole mindset that fps bullets magically go
exactly where the shooter perceives his sights to be when he pulls the trigger. But that is for another topic......
