I was messing with the options today and i turned the lighting down to static and sure enough i went from 30-40 FPS on minimum to 80-120 FPS solid. Now i can play on maximum and i get a rock solid 50-70 FPS on the system in my sig.
With static lighting you lose shadows and the lighting is not as great but the rest of the game looks fantastic and runs very well.
