    I'm sorry you're experiencing issues with the Compute benchmark. Could you tell me which driver versions you are using?

    Same with 376.33, was using 376.09 before and had the issue aswell.

    Btw it happens to other ppl, I just tried again, still getting 0 and noticed three others, with other GPUs:

    Same problem with a GTX 1050 Ti. Sobel result is zero. All new computer build with all hardware on latest drivers.
