Thanks to all. On this website there are so good tutorials! I tested today my cap with a game....it's awesome, it's very very funny to play with freetrack activated. Looking forward to GRID compatibility.
I will have to practise very much with movement configurations and sensibility...i don't know how to use that curves of graphics (yaw, pitch etc...).
but thanks!
