Same thing here. The game runs fine up to that point, but when i click the strategy map in the beginning of chapter 2, the framerate goes into a crawl at once and stays that way until i load the game. Fiddling with the graphics settings and so on does nothing to help. I also have a dualcore processor like other people in this thread (Core 2 Duo E8400). The funny thing is, the game ran fine on high settings before that point (the game itself started that way when i installed it, and i never had a reason to change any settings before chapter 2). Anyway, it's nice to hear you are working on a fix so soon!
