Aiming left / right acceleration greyed out in settings

That was an absolutely not helpful comment. Literally helped nothing or no one in solving this issue

Your welcome glad it helped out

buddy I own you, I done exactly what you said and it worked for me too … nice one thanks! 

good afternoon, change your vehicle stick input acceleration presets settings to BF1, change your left/right acceleration here and then you will see that in infantry it is also now enabled. 

On bf2042 yes but on bf6 accl for bfbc, bf4, bf3 is greyed out, you cant chabge it. 

I had the same problem, I was able to adjust it and set it to 12, I accidentally hit reset and when I went to change it to 12 it was grayed out, I went through the other settings and it's in Ground Vehicles settings, if your reset the ground vehicles settings back to default, then go back to soldier settings and you will see you can now adjust it again 

What happens is the ground vehicle settings takes over that setting and gray's it out, bug I guess.

Nope I use to be able to change it no matter what I change in the other settings, doing reset, it is always greyed out.  So frustrating 

Got same problem on my ps5. I was able move it before then became unavailable. 

Its not a bug i use the same accel input, its locked at zero for this one, change it to something else, youll see what i mean!:)
