General overview for Wheel/Controller settings:

Vibrations:
This slider allows you to control the vibrations intensity. It goes from 0 (left) to 10 (right).
With an intensity of 0, you won’t feel any vibrations. With an intensity of 10, vibrations will
be as strong as possible.
Force Feed Back:
This list contains eight values. The Medium value is set by default so you can feel a normal
force feedback. When you drive, the wheel should try to move to its original position. You
should also feel various constraints depending on your driving and the car’s specificities.
The Low and High values are variations of the medium value: depending on your wheel and
your preference, you may want a strong force feedback or a light one. Note that you can still
change your driver’s behavior in the windows’ options panel. Most wheels (Logitech’s for
instance) are sold attached to a specific software. It should allow you to perfectly tune your
wheel’s force feedback.
Without any surprise, the Off position will leave you with an inert wheel. There won’t be any
force applied to it, not even the default “return to center position” force.
Default position will set a constant “return to center position” force. Even if your car is ten
meters above the ground, this force will still be applied.
At last, the “inverted high, medium and low” positions will mainly behave like their non
inverted counterparts. The difference lies in the “center position” which won’t be a 0° turn but
something more like a 180° turn. Those positions should only be used by possessors of exotic
wheels encountering very strange behavior while using classic force feedback. In other words,
if you wheel have this behavior when you accelerate, inverted force feedback will save you :
Controller linearity:
This slider isn’t useful if you play with a keyboard. Improved in the last version, the slider
will go from 0.5(left) to 3(right), with a step of 0.25. But what’s the meaning of those values?
The steering input is elevated to a power equal to the controller linearity value. Previously
you only could go from 1 to 2.5. Default values are still 1 (for wheels) and 1.75 (pads). Those
diagrams represent the transformation of the input depending on the controller linearity you
choose:
- Green: slider on the left. Output = input ^ 0.5. The first degrees of the wheel are very
sensitive. On the opposite, the rest of the wheel is very precise. Ideal for 700-900°
wheels.
- Blue: slider on the left. Output = input ^ 1. No transformation.
- Red: slider on the center. Output = input ^ 1.75. Ideal for pads.
- Black: slider on the right. Output = input ^ 3. The first degrees of the wheel (or small
move of the pad) are very precise. Last active degrees of your wheel will be very
sensitive.
If you wish to force your wheel to 700° or 900°, you should probably set linearity to 0.5 or
0.75. Otherwise, wheels are used in a 200° range roughly, so standard linearity of 1 should fit
perfectly.
Steering damping:
This slider allows you to control the maximal angular speed of your wheel. The speed
limitation can be removed by positioning the slider on the left. It is recommended for wheels
as it removes the “lag” feeling. If you move the slider to the right, your wheel will turn slowly
at high speed, thus avoiding frequent spin around. At low speed you shouldn’t see any big
difference. With pads or keyboard, you should keep it between 1(nearly extreme left) and 10
(extreme right).
I.E: If you move the slider on 10, at 300km/h your wheel won’t turn faster than 130° per
second, meaning you’ll need 1.5s to completely turn your wheel.
Dead zone:
Steering wheel doesn't need any dead zone, and in this case the slider must remain at the
minimum value. If you use a worn pad, the central position may be damaged, and you can
increase dead zone to keep a correct driving behavior. It won’t change anything on keyboard:
a key is either pressed or released, there’s no variation on which dead zone could be applied.
Clutch, throttle and brake linearity
Those sliders aren’t useful if you play with a keyboard.
They’re similar to Controller Linearity. Input values are elevated to the slider power. Central
position is ok for all the devices. If it’s too sensitive, move it to the right. If it’s not
responding quickly enough, move it to the left.
- Green: slider on the left. Quick response, no precision.
- Blue: default value, slider on the center. Linear response.
- Red: Slider on the right. High precision but forces you to stamp on the trigger or pedal
to have full response.
Clutch has also been improved to allow easier gear shifting.
Hopefully patch #1 improves FFB and game exp
