No problems in the demo but in the full release i have a problem which i think is Input lag.
Sometimes when i turn it turns to late or sometimes it turnes even when i was done with turning.
Makes online racing near impossible so I hope there is a fix for it.
I have the same problem and would love to know how to fix it.
I have the same issue! 
Yep same issue kinda makes it frustarting to play like one second you driving and having fun the next second you find your self inside a tree sighing or even inside a tractor, just cause the game decided to hold A while you were tapping A
