I just got NFS Pro street, my specs are A8 6500, 6GB 1600MHZ RAM, Radeon 8570D. I have it with a low res. and lowest possible settings, i game boost it using Razor game boost and still doesnt help. It says I have 120FPS average even while racing, but is a laggy mess. The FPS, i notice is dropping immensely. I can run Mafia 2 with zero lag with fairly good settings and a 1600x1050 res. and gta iv with some lag but playable. Even in the menus and such it lags? How do i fix this?
