As I said I'm running on an i5 so it's not a dual core and my Catalyst Control Center is running AA on "use application settings" so it's not being forced. I saw the topic linked but figured my issues was a different one, also unlike the people in that thread my issues don't start on chapter 2 but on chapter one. On the first strat map I notice a significant hit to the frame-rate.
Edit: Also I just attempted to play with AA turned off and it seemed to have no affect on my frame-rate issues.
