Snow Leopard: Macbook Pro Video Card switching + SLI

[lupin.terzo]

Hello guys! I own a 2009 Macbook Pro. I was just wondering 2 things about Snow Leopard:

1. How does it manage video card switching?
2. Does it allow SLI?

Appreciate your help.

Thanks,
Andrea

1. Same as Leopard. Some apps don't like video cards being switched out from under them, and Apple apparently feels protecting users from this is worth totally disabling on-the-fly switching.

2. No, and nor will it ever. There would be no point, as the 9600M would have to scale down to less than half it's capabilities to pair up with the 9400. This would result in worse performance, not better. Thus, the 9600 does NOT support this in hardware.
