I've been through the readme of te game and looked at posts and such. But one question I have is that, how can I set my controller? I haven't been able to find that in the game, I can't stand driving with my keyboard and I want use my controller. Can't find any in-game or out of game option that lets me set my controls for the game....

start a race then press escape, go right with your KB on the escape menu, go to controls, on the upper you will see KB and some icons kinda like < & >, click right then select your controller, program it and you are done my friend!
