Good night, I'm having problems running in oval circuits, on the straight cars the cars go well, the curves start to shake and my car jumps back, I've reduced graphics to the minimum and I can not solve. my settings: amd fx bulldozer 6 cores 3.3ghz 8 gb ram geforce gtx 650. Someone already had this problem and managed to solve ??? before I could run on the same tracks without problems.
