    Hey there,

    does anyone know how to get Photoshop to run OpenGL on the 9600M GT?
    Does OpenGL always run? Why won't Photoshop recognize that I can use OpenGL?
    Apple and Nvidia has no drivers to help me out... :( please shed some light on a new MBP owner!

    I believe like all apps on the mac, the feature is available to be used w/o any interaction with the user. In other words if you have a compatible card (and you do) PS will automatically start relying on the GPU more the the CPU

    I believe that's right, but you can manually enable/disable OpenGL in the "performance" section of OpenGL.

    You'll also generally notice a slight shadow on the bottom and righthand side of the image if OpenGL is enabled for that image, which is absent if it's not. (Although this setting can be changed too, apparently.)

    If OpenGL is enabled and you open too many images, it will also give you a message telling you've exceeded the maximum number of OpenGL-processed images. This may be higher for newer models, but for a machine with a 8600GT, the default max is 15 images.

    Hope that helps.

    thank you

    well that sounds like mac alright, haha.

    the only thing is my Photoshop preferences has OpenGL grayed out.
    how would I control OpenGL outside of PS?
