It isn't supposed to be easy just real... The first time I used Sim. Steering I remembered goofing around in my parents car(1988) and getting into a fish tailing tank slapper.
Unless you drive your car with a Gamepad, it's not "real". And it doesn't affect in any way, shape or form the physics of the game.
All sim steering does is turn off input smoothing - which is incredibly useful in certain situation (i.e. oval racing, drifting) where you may need to give very small steering inputs, and counterproductive in most others.
I don´t care about the result, so is Turn10 doing things to its laserscans to make the endresult inaccurate ect, i just want to know and share my findings
Turn10 claims they have been taking laser scans of circuits - however, I'd bet they only did that for some tracks, and approximated their modelling anyways (i.e. by re-using the same kerb profile on different kerbs). If we go by Chris Esaki's words, it sounds like they actually intend to walk the walk this time, but Í'll believe it when I'll get my hands on Forza and I won't be driving on a bizzarro-world version of Road Atlanta or the Nordschleife.
