Maybe they are letting multiple threads access same memory and also writes to that memory. This is a situation that C2Q isn't able to handle well. When games are optimized for PC's I think it mostly is optimized to scale well on C2Q and also do the main work on two threads for C2D. C2Q don't like threads that talks to each other and shares resources, each thread should handle be as "single threaded" as possible.

If threads shares resources, then there will be a lot more FSB traffic.
