Can't turn off controller look acceleration (PC)

Changing Controller -> Sensitivity & Acceleration -> Look Acceleration to “1”
Doesn’t remove acceleration. It’d be nice if there was a “0” value of some kind. For me personally playing with any kind of acceleration makes the controller experience unplayable because as soon as you start turning around a bit you suddenly start turning more uncontrollably.
There’s a ton of deadzones and even separate sensitivities for all the different zooms, plus KBM does have the option to turn off acceleration, which plays very well.

Agreed, there needs to be at least an option for zero look acceleration on controller.
