Playing gta 4 on my new mbp

[wondering]

Hey guys,

GTA 4 is running quite slowly on my mbp eventhough i surpasses the minimum requirement, I play it on windows vista.. I suspect that the it uses the integrated 9400 instead of the dedicated 9600m graphics card..

Is there any way to switch between the two cards in windows?

Can't use the 9400M in boot camp, assuming that is what you're doing right? The GT is default and only one we can use, hopefully with Snow Leopard we get some form of hybrid SLI.

Windows can only use the 9600 currently, theres no way to get it to use the 9400 yet.

From reviews I've read, GTA IV is very optimistic in how well it will run when it auto sets the defaults, will probably have to turn details down a good ways.
