The graphics are better in AC already in my opinion, although AC doesn't fully support FFB yet so yeah nKPRO is quite good. However the physics are difficult to compare as AC currently has just 1 car and track to test.
No, no. Not a drift meter, sorry It measures _longitudinal_ slip instead of lateral slip angle. I'm purdy sure there are some actual drift meters on the official forum's modding section, if not already in-game by default. Think of it more as a traction control indicator. Anything past "" means that you're spinning the rears too much.
If anyone is legitimately going to try it at some point, values of 2000, 3000 & 6000 in the config work better than the current defaults.
Yah so unless, like Mr Skypimp said, there's some odd mixing up going on in ac where it's applying sidewinder settings, and inherent limitations, to the other wheel then it's more likely to be a setting in his primary steering wheel profiler. But like I said it would be hard to miss a setting like 180° rotation, so who knows.
