Hello, I'm a user from Hong Kong and I've a huge problem about Photoshop.


I've a 15" MacBook Pro (Graphic Card is 6490M) and installed Mountain Lion and Photoshop CS6. When I Check my System Info in Photoshop, it show the OpenCL is unavailable just like this:

Then I open the Performance tab in Preferences, and see that I cannot enable OpenCL and the GPU Acceleration like this:

    Open CL is a function of your video card and driver.  It is a little flaky and not as important as having Open GL.  If the latter is not working you will miss out on a lot of bells and whistles.

    Either your GPU isn't up to it, or the driver isn't up to it.


    Mobile parts are usually more limited, and Apple's 10.8 drivers aren't exactly the best either.
