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.
Your CPU is struggling. You need to make sure you have nothing in the background using CPU. Some more recent cars use better tyres that will make your PC work harder, and some recent features (rain related, car damage related) will also be causing an issue for you. If you can upgrade your PC you will have more luck. Your CPU has quite low performance per-thread (less than half a modern 3.5GHz CPU), my last CPU had similar performance and I wasn't able to run rF2 properly anymore.
