PS3 Controller

Hello!!! I had plans on buying the boxed version but due to that I live in Denmark and the shipping stuff etc. etc. from Germany I have decided to buy the download version of the game in Friday! I don't like to control with the keyboard, so I want to hear:

Can you use your PS3 controller?

Windows recognizes it, but for using it I have to use MotionInJoy (in other games). Do I have to do this too in OMSI?

Thank you in advance, and I can't wait to get the game, watched some YouTube videos and that's just fantastic!
