I don't think I'll ever understand why every racing game I play seems to default to such massive controller deadzones. DR2.0 defaults to 20! Why? You've robbed so much accuracy from the controls, for what reason? To account for people with absolutely knackered controllers? My pad is no spring chicken and doesn't see any drift input on about 4 clicks. If your controller is seeing drift up around the 15-20 mark, then it's fit for the bin! Maybe prompt players to perform some kind of calibration on start up?
The advanced settings need descriptions too. It's almost impossible to tweak these without knowing *exactly* what they're doing to the mapping between input and in-game steering. It would be useful to move the input display sliders to this page also so you can see them in real time.
