    Sorry if this is beaten to death, but:
    I noticed that in their resting states, Safari 5 only enlists the onboard Intel 3000HD, whereas switching to the same webpage in Chrome 10 recruits the 6750m automatically and kicks the GPU temp up 10-15 degrees C.

    Does anyone know if future OSX updates will likely make the automatic graphics switching algorithm "smarter", or is it a basically stillborn feature?

    It's kinda lame to have to hang on to Safari if I want longer battery life when I'm unplugged, because I'd almost finished switching over to Chrome and would prefer it...

    try out gfxcardstatus

    you can force chrome to use integrated (intel) over the 6750

    This has been discussed numerous times on this forum as well, and it's been an issue since the 2010 model.

    Basically, new browsers like Chrome 10+ and FF4 call OpenGL since they initialize WebGL when they startup. Sometimes this dependency will disappear and the browser MAY revert to Intel, and then it might call OpenGL again.

    My suggestion is to use Gfxcardstatus to control your GPU by hand.

    This. Here's a thread that explains what happens (they forget to mention the WebGL stuff, but you get the idea).

    Chrome Forcing Dedicated GPU


    Send some feedback to Google's Chrome development team and see what they can figure out.

    Sweet. Yeah, this seems like something that could definitely be improved. I imagine the discrepancy in battery times some people are getting could be attributed to them surfing on chrome.

    Thanks! Henry B @ Google seems really helpful. Apple needs someone like that... lol

    Some mode should make a sticky thread.
    AutoGPUSwitching sucks the Apple way use gfxcardstatus.

    Google doesn't need to do a thing they use the libraries and the should. Intel GPU could drive them usually fast enough. Apple should just make some white list approach to switching that would work always, better and could easily be customized.
    The worst is Skype (sitting idle doing nothing) but even with forced Intel it reduces battery life so much that I usually kill it.
