    Hi David,

    Could you please give me more information on your current situation? What sort of error messages are you receiving and what are the spec of your computer. The GPU test is located in the Compute tab on the left hand side of the program. Please try to run it with all other apps closed, and your device connected to power. If the problem persists, let me know and I will look into it further.

    Hello Ariella,


    Thanks for the prompt and courteous reply. I’ve attached a screenshot of the GPU (Compute) image, on the windows version I can select the GPU to test, as well as the test type (OpenCL, CUDA). I am not given that option on the MAC. When I press the Run Compute Benchmark button the screen goes away and immediately returns.


    Here’s a link to the CPU tests which were successfully run.


    Please let me know if you need more information.


    Thanks again,


    David Young

    Hi David,

    Thanks for letting me know about this issue. I'm going to file this with our engineering team so they can take a look at it. My apologies for any inconvenience this is causing you! As soon as I have more information about this, I'll follow up with you. In the meantime, please try a system reboot. If it does start to work, please let me know.

    All the best,

    Also having the same issue here. The test seems to get through Sobel and then as soon as Histogram Equalization begins the test quits, but the application remains open.

    I can't run it either.... it doesn't allow me to select a Compute API or a Compute Device. At the bottom of the window it says...

    "No compatible compute devices found"

    In my case, I'm able to click the "Run Compute Benchmark" button, but the test fails shortly afterward.

    It is because of NVIDIA web drivers

    Tried V 4.1. OS X El Capitan , Nvidia Web drivers (newest), CUDA drivers newest
    Same, only OpenCL compute rnns well (14000 Result)
    CUDA - click run does nothing, no error message, also nothing in the console log!!!
    Metal (new) - same as CUDA, run does nothing, no error messagealso nothing in the console log!!!
    Metal in generall works for me, no problems running some Metal benches.
    Same is for CUDA. no problems.
    I think there should be some debug code added to figure out what goes wrong.

    testing a range of mac to compare, but not able to run graphics test on MBP5,5 with Nvidia 9400M (see attached screen shots) - other macs are being tested fine, so is this MBP just too old? It's not a big deal, just curious.
