Second change was this, default was 0.3, but with this 0.8 I don't get any oscillation that I could notice and when stationary tires 'stick' to ground more like they should.
Steering torque zero-speed mult="0.80000" // Multiplier at zero speed to reduce unwanted oscillation from strong static aligning torque
Every situation I have clear force feedback, but test how it feels, I use G25 and I find these changes made ffb to feel more natural to me at least.
Funny thing is that steering resistance is what affects to much more than just resistance to turn the wheel, but I can easily feel now when braking how close to locking my wheels are, I have been running 100% brake pressure and 55/45% brake bias.
I'm not very good driver but I got 1:52.9xx at Malay, messing up most of the corners, I don't really know how terrible slow that is, but probably quite slow.
