No it doesnt, FFB gain does that.I think it simply adds or reduces weight to your steering wheel.

As far as I know its a gamma curve for the FFB signal, so 100% is completely linear. Its used to try and reduce the FFB amount at high speed, so you can get decent feedback at low speed without clipping at high speed.
If you have a decent wheel, I wouldn't bother moving away from 100.
