Hey guys! just downloaded the game yesterday because I heard good about it, and I got my registration code and all and everything went smooth, but my game seems different from everyone elses game I see on youtube.
I have version 1.10, which I checked is the latest version, and the controls are horrible, like I cant turn or do barely anything it seems, so I figure that must be in the settings, but I would appreciate help

I see people on youtube that are ridiculously fast and it looks so flowing and such and I couldn't get that if I tried, lol. and also, I see all the content on youtube with an abundance more tracks and bikes and stuff than what I have, is this all DLC? if so, where do I download it all, and is it free or some is free others not or what? im pretty sure I have the right game it just seems the bikes look AWFUL like the first version awful, and the bikes and tracks online look so real and much nicer, just wondering if that's DLC or graphics settings or what im doing wrong.
ANY tips to get me going faster is MUCH appreciated as I would love to jump in and start getting good, just ALOT of stuff and overwhelmed and would like some advice from the pros
thanks again all
