TOPIC: Wheel sensitivity vs linearity

Wheel sensitivity vs linearity 19 Apr 2020 08:26 #114209

Can someone please explain the difference? In “advanced settings” I see 3 options: dead zone, linearity and sensitivity.

I understand dead zone sets the amount you have to turn the wheel in the initial phases of turning before the wheel actually starts turning.

Linearity seems to be the angle you must turn the wheel in order for it to turn a certain amount.

But then what is sensitivity?

Sensitivity is how much you turns when you turn your wheel.
For example:
  • when sensitivity is 1.0, the steer IN GAME turns 20 degrees if you turn STEERING CONTROLLER 20 degrees.
  • when sensitivity is 2.0, the steer IN GAME turns 40 degrees if you turn STEERING CONTROLLER 20 degrees.

    Linearity is how sharply you turns when you turn your wheel.
    For example:
  • when linearity is 1.0, the steer IN GAME turns 20 degrees if you turn STEERING CONTROLLER 20 degrees, and turns 60 degrees IN GAME when you turn STEERING CONTROLLER 60 degrees.
  • when linearity is 0.0, the steer IN GAME turns 20 degrees if you turn STEERING CONTROLLER 20 degrees, and turns 300 degrees IN GAME when you turn STEERING CONTROLLER 60 degrees.
    Notice how sharply the steering in game turns as you turn your steering controller more.

    If you are familiar with math, the relation between rotation angle of input and output can be written as:
    y = a * f(x)
    where x is the turn angle of STEERING CONTROLLER, and y is that of IN GAME. Then, the sensitivity corresponds to a. The linearity decides the function f(x), such as f(x)=x for linearity=1 (you know, it's linear function.), and f(x)=x^3 for linearity=0.
