Have you tried verifying the integry of game cache and defragmented cache files through Steam?
Did you download or buy it retail? If retail, maybe it's worth it to reinstall if you haven't tried already.

What are you PC specs?

Already did the game cache thing. 

PC is core-i5 3570, gtx 570, 6 gb RAM
