I've got an Intel, 10.5 Macbook Pro with the Gefroce 8600M GT. CSS runs horribly, though. Dual booting in Windows XP/Vista can run it with max detail, Parallels barely runs it at minimal settings, and Crossover runs it just OK on low detail settings. The worst part is the mouse speed slows down when the framerate is low. I've tried different bottles, as well as CrossOver Games. Any tips?
