    So I have a 2011 macbook air base model (2gb ram, 1,6ghz i5, 64gb ssd).
    It's blazing fast for everything and the only time it slows down is on Preview.

    But it slows down a lot. Not only while editing photos but for example, I had 3 e-books in PDF format , which I opened from safari using "Open in preview" in order to download them permanently.
    The saving is fast, but when I closed each of them , preview got stuck for like half a minute with a spinwheel.
    Why does it take so long to just close a window?
    My ram isn't even full (500mb left) and cpu is working at 16-25% speed.
    So is it the GPU's fault?

    Also, because of the low ram (2gb), intel's HD3000 only has 256mb memory, instead of the 384mb on the 4gb models. Is there a way to change that? Make it use more ram, since I don't need it anyway?

    Yes, it's the weak HD3000 iGPU, which is relatively slow in rendering video. Sandy Bridge TurboBoost can't make up for that.

    I guessed so... But is there a way to give the iGPU more available ram, or is it locked at 256mb?

    Sorry to bump this thread but I couldn't find anything by googling it.
    Is there a way to give the iGPU more available ram than 256mb? Or is it locked in a certain memory depending on the available ram?

    How on earth would a weak GPU make the Preview app do a 30 sec beachball when exiting the app? I can promise you that's not the cause.

    Not sure what the problem is, but something is broken with Preview. I would try a reinstall of Lion, that would probably fix it.
