hi Jordan! Sorry I might not be much help right now as it’s been a while since I dug deep into the code but IIRC, Sinput.mouseSensitivity is a separate setting to what users can adjust in the rebind scene (I might be wrong though, but it should be easy enough for you to test with what you are doing now?)
I do know that you can (and in a few cases *should*) separate mouse and gamepad inputs for things like looking around, Sinput has a PrefersDeltaUse() function for this (check the “Framerate Independent Inputs” part of the documentation here) - generally, if this returns false then the input is from a mouse (on the frame you’re checking, if they switch to a gamepad stick it will become true), and you can multiply the input by your own scaling factor within a conditional.
I hope this is some help! If not let me know and I can try digging through the code for a refresher so I can give a better answer :)
