World scale is the problem ofc. I do measured my ipd, I did set it up in to the oculus. I did stand up for the sensor calibration and the world is smaller. I have been searching all over the net, I have checked so many forums about that and no real solution. To be 100 sure a went on a few tracks to drive and check the size/real world scale... , well nordschlaife is totaly zoomed in AC and smaller then in real life, approximatly with 20%.For further tests I picked sims where you can correct world scale, and guess what? I felt it much more natural, and very realistic as when I was driving it in real life,by increasing the world scale.One more interest thing I found out, on Sims as Iracing with default fov 45(I know that fov is not working under Vr) Nordshlife locks very close to the reality but still a bit smaller may be 2-3%. AC with default fov(54) - Nordshlife is zoomed and small like 20%.Raceroom epx default fov 56,more zoomed and smaler then AC. I am still looking for the correct answer, until I find it, I was looking for someone to implement world scale in AC.
