deadzone=0 might be suitable for controllers,
but we do not think it's the same story for keyboard and mouse control.
for if deadzone=10, and when console gets a 11, it will also give you a speed=1(the slowest speed on screen).
when cross hair detect the slowest mouse speed,
it will translate that to 11, and let you have the slowest speed(1) on screen too.
for if deadzone=0, and when console gets a 1, it will also give you a speed=1(the slowest speed on screen).
but all the embedded parameters in pubg preset are trained based on deadzone=10,
so if you change the deadzone in game, you will not get the best control.
All our preset configs are trained on the default deadzone, please kindly note that.
