    Hi,

    I have a question which I have for a very long time now.

    I own a Macbook Pro Retina 15" Early 2013, and since I have the Macbook, I experience some weird lag in launchpad, mission control, and in the raster application folder in my dock.

    I am running Mac OS X Yosemite DP6, but it has been there with Mountain Lion, and Mavericks too.

    I have found one solution for now, and that is running running Photoshop CS6.
    When I run PS, it starts to get all smooth, which is... quite odd in my opinion.
    But I am really wondering if there is another solution than running PS to get rid of the lag in launchpad, mission control and the application folder in my dock.
    I have been looking around for a long while now, but cannot seem to find anything which actually worked. (Like cleaning VRAM).

    I hope someone else can help me out with some suggestions.
    Thanks a lot in advance.

    Yes you have another solution.

    Photoshop need to use your discrete Graphic card ( which is nVidia GT750M, in your case) to accelerate the graphic speed performance that's why you feel smooth when you are on Photoshop. and you feel some lag is because your OS is on integrated intel ****** graphic card.

    go to system preferences -> energy saver and disable (uncheck) automatic graphic switching and the OS will stick with the descrete card.

    Think Photoshop forces the discrete graphics card, so it's likely the discrete graphics card is making the machine run smoother.

    Thank you.
    Seems like a logic thing to me indeed.
    So what it actually does is that Photoshop is forcing the graphics card to use more of its power when it does when Photoshop is not running?

    If there would be an option to do this without running Photoshop, than it would mean that the battery life is much shorter too, right?

    Although, I would like this option anyway when I'm on the adapter ahaha

    See airlied's post on how to disable automatic graphics switching.
