I downloaded the graphics info app to find that my dedicated graphics card was on all the time. Afte some testing I realized it was firefox 4 beta 12 that was causing it. I have no addons installed and simply launching the app causes the graphics switch. Not until I explicity kill firefox does it go back to integrated graphics. Safari does not seem to have this issue. Any suggestions?
