About the sensitivity part , you have to figure it out yourself . for me 9 feels like 45 in bfv which is i used in that game . Maybe this could get u general idea how to set it.
ADS sensitivity in my test feels like 10 is equal to 10 hipfire , so if u want to have 1:1 sensitivity u might want to do that.
About the inner deadzone part , as far as i know and base on google research , Borderlands uses a square instead of circle so if u put 5% on a different game and put exactly 5% in Borderlands , u aren’t getting the same deadzone because square is bigger than circle , to some what fix it u gotta lower to a bit , for me it will be from 5% originally to 3%
about outer deadzone ,as the description said the lower the value of the outer deadzone the more input require to achieve max input . the default value is 1 , i would suggest not to mess with it. but in my test i felt like it sort of disable aim acceleration if i put it on 0 , my explanation is if i put it on 0 i will never reach acceleration threshold , do that or not , thats on you
about axial deadzone , people say its bad it make yourself harder to aim . i say otherwise because it makes my aim less shaky . you are controlling the stick with a thumb logically making very little movement is gonna be kinda shaky . i would suggest you lower it from the default 0.5 to between 0.3 to 0.1 . and apparently if u think otherwise u can just put it on 0
i really hope this thread gonna help people out who having trouble with their aim. if u practice enough u can play the game without aim assist like me
