Installed Snow Leopard last Friday and have to say the biggest performance increase I have noticed, is when I've run Football Manager 2009. The 3D match engine seems smother and the load times between actions is definitely reduced. When I played it in Leopard I used to notice a big difference compared to when I played it on my PC, now the experience is very similar between the 2 computers. Was wondering if anyone else who has SL and FM2009 installed has noticed the same thing?
