When the MBPs came out with the dual graphics cards, people believed that they would be able to fast-switch between then. However, this is not the case; a logout-login is required to switch between the 9400M and 9600M GT on the MBPs. It was thought with the release of Snow Leopard this would be fixed. So, has it been? will it be? Any word on using both graphics cards at the same time to boost performance?
