Magicfr, Seb, this looks fantastic, exactly what I am looking for! I've been racing Race07 and its likes for the last years, because I couldn't find any other sim that had proper g-force simulation. Accurate movement of the cockpit/car with respect to your head is absolutely necessary (in combination with force feedback) to be able to instantly judge what kind of forces are working on the car (and also when you are losing grip for example). I've been doing a lot of track-days myself, with a helmet mounted camera, and you have a very pronounced movement of the car with very little movement of the track on the resulting video.
I won't buy Rfactor 2 if proper gforce simulation is lacking. This mod might do the trick, the videos look great. Developers, please implement this feature in the sim itself, because the standard camera looks awful in the videos that have been distributed!
