Would this be a valid theory guys?
Maybe it's changed, so when you choose simulation options for your wheel the game automatically set's itself up to "pro/sim" physics. I mean, what's the point of making that choice twice? If you choose simulation settings for your wheel, you wouldn't choose arcade physics in the race menu right? And then, you say, what about people driving with pad, aren't they going to be able to drive with pro physics?
Remember the TT demo? Pad users were forced to have AIDS on, now it wouldn't be very strange if they're now forced to play arcade physics instead (kind of the same thing right), since almost all pad users are casual gamers.
My theory, wishful thinking I know but it makes sense.
