So...what things you don't like about this game.

Holy mother of this
Also no brake glow, which saddens me

 

Sorry, I wont take you seriously since you literally criticize a simulator for its difficulty.... while using a keyboard.

But to actually answer your thread, the UI is super laggy which sucks a fat lemon, the crash sounds should also be improved.

I must agree completely. You can definitely feel how a front and rear spoiler affect the handling. Its a great sensation to have a car with a crapload of downforce and the feeling of the car being glued to the road.
