@ scitek - Same here. Game is playable with a framerate of anything between 35 and 60 fps but as soon as it dips below 50 fps then it feels horribly laggy and jerky, especially when cornering. It completely spoils what is otherwise a really good game. Lowering settings doesn't fix it either, only reduces it slightly. I cannot believe that Criterion have still not fixed this issue. I refuse to believe that this is a result of CPU limitations as other games feels far smoother at 45 fps than this does; Sleeping Dogs for example which I capped at 45 fps due to the Extreme AA making my GPUs run hot during the summer.
