    Does anybody experience any delays with the auto graphics switching on the late 2010 MBPs? I mean serious delays?

    Mine seems to be very slow at making the switch. Say if I open a PDF that has a load of images in and start to scroll at high speed to scan the document, everything becomes very stuttery. Then, after a while (very random in how long it takes) everything starts to get smoother, when I assume the NVIDIA kicks in.

    I thought this was meant to be more-or-less instantaneous?

    I would think that has more to do with your computer still opening and loading the pdf?

    Good point, but the PDF could be open for a while and I've already scanned through the document once before.

    Also seems to do this on websites with Hi-Res images or Flash objects.

    I don't think it's the graphics switching. It's probably just the GPU (whichever one's on) trying to render all those images as fast as you're scrolling, except that you're "winning"...after a while it probably pre-loads them into RAM or something, which speeds it up, but still...

    Try to scroll by pages, or jump to the page you need instead of scrolling all the way down one line at a time as fast as you can.

    it has nothing to do with graphics switching.
    for graphics switching to kick in either OpenGL or OpenCL has to be called, neither of which are called to open a pdf document.
