Switch graphics cards in the MacBook Pro

The new MacBook Pros have two graphics cards. The good one...and the crappy one. But the good one is hell on your battery, so you probably want to use that one only when you're plugged in. Here's a Quick Tip on how to switch graphics cards in the new MacBook Pro. Let's say I've been out and about using the power-friendly integrated graphics card, then I start playing a game and realize, hey it looks ...bad. Go to system preferences. Choose Energy Saver. See where it says graphics? Choose High performance. Here's the bummer: it requires you to log out. So save that gameplay, word doc or whatever else you have going on, then choose log out. OS X will log itself out, switch cards, and log back in. Then start your game back up and enjoy the better graphics. That's it for this Quick Tip, I'm Tom Merritt with CNET.com.
