This Game is damn well optimised!! I was able to keep up with 50+ FPS at all times at lowest settings( except for multi sampling at max). If turned to medium, still 35+ FPS without any question. Only issue is with the less number of cars you see!! But dev's did try to get Ferraris and Lambo's but could not.
