The Macbook Pro has two graphics cards, one which is built in and another one that is more powerful.

I installed XP Pro using bootcamp. Which graphics card is XP using, and how can I switch the graphics card that XP uses?

To switch your graphical card, go to Energy Preferences and select the other "profile" on the top. It's counter-intuitive, I know.

To see your graphical card on Windows, as people already pointed, you have two options: press [Win Key] + [R] and type either "dxdiag" or "devmgmt.msc" and look for the "Display".

I believe there's no way to switch card in Windows, tho. I've read it will always use the only most powerful one. Which makes some sense - why else would you run Windows on Bootcamp if not for playing games?

Look in the Device Manager in XP, under Display Adapters. It'll show you which one it's using. As for switching, I have no idea. Not sure Boot Camp can do that. I also don't think XP would support switching a graphics card while it was running. You'd most likely have to reboot.

Start > Run > dxdiag > System and Display tab

You should get a wealth of information on which graphics card XP is using.
