Seriously M1eX i think you should just get your money back from the preorder, i too got the g27 for racing sims (or even tdu1 is great with it) and the possibility of wasting your money on this game is just not worth it at all. The amount of problems with the wheel support is just really bad, the brakes suck, clutch useless, force feedback just plain stupid, and when you center the wheel it just like auto sticks going straight (like on rails), with a bit of a deadzone (which i tried fixing to no success). If you think about it all the preorder gives you is a bonus car, which is not bad but not worth the risk. I would wait abit for a response from atari about the (undeniable) amount of complaints they will recieve, but then again judging from what they said during the beta its probably not looking good.
As much as this pains, they failed the sequel and its not worth it.
(god i hope they make me eat my words)
