Unsure if it's been reported once before or I am having some strange issue but when the "enable sprint aim penalties" option is disabled I get a ton of weapon sway regardless of my character state (standing ,crouching, prone) and weapons stats have no effect. I tried adjusting the weapon sway intensity to counter act this and this also seemed to have no effect so I thought I would bring this up in the event that this is a bug or a weird interaction of some kind
I did some testing of my own trying to figure out if there was some weird mod confliction going on and was unable to find anything. I put the mod by itself in a fresh install and tested the setting and got the same results if this helps at all.
