Controller settings are so complex.
First understand how “Max Input Threshold” works. It, from my understanding, changes how far you need to move the stick until acceleration increases.
So if you have it maxed out, it will increase acceleration slower as you move your stick; this is usually not recommended since if makes turning inconsistent and messes with your aim adjustments.
If you have it on 0, the acceleration will not be noticeable, since the amount you must move your stick is nothing.
When I have this on zero, I usually put acceleration on max (5)
“Max Input Threshold” should not be the same for both move and aim (I have move on 10), because you want your strafe and movement to compliment your aiming.
Next,
“Center Deadzone” ideally should be on 0, but needs to be as low as it can without drift occuring.
“Axial Deadzone” should be a littler higher cause it makes it too response where you lose control of aim. I just played around with it until I liked it, which settled on 7.
Finally, you can just set your sensitivity really low for more control. Mine’s on 1 or 2. Also, I recommend trying Vertical with different than Horizontal, like 1 more than it or something. It sometimes improves aiming control.
Zoom’s, I suggest leaving on 1
There are many controller setting ideas out, so this just mine.
