I first saw this on Engadget. Apparently there's a utility called gfxCardStatus that shows you if your 2010 i5/i7 MBP is using integrated graphics or discrete graphics and now allows you to switch between them at will. The feature is experimental, as the site stresses, but it seems stable enough if you only wish to use it once in a while as I did. (I tested a game that didn't trigger the discrete graphics with the discrete graphics forced on) If you can't wait for Apple to get their game on I suggest using it. Enjoy. P.S. Yes, I know my post shows all the characteristics of a spam bot post, but I assure you, I come in peace. Here's the original article by Engadget if you don't trust me.
