How to check CUDA effective workload?

  • July 10, 2017

I have installed a brand new GTX1080ti on my Windows 10 system, with CC2017 suite

When I start rendering (of course with Mercury GPU acceleration selected) or exporting i see all may CPU cores (Intel cores i mean) go up to 100%, and al the case FANs increase airflow; but the GTX temperature, fan speed and GPU usage remains very low (I can see this with the ASUS GTX monitor utility).

Have I to think that rendering is not working with my card? How could I check this? Have I to set something special as I have done in the past with a GTX670?

Thanks all for any idea.

    I missed that you already have a means to monitor the usage. If it is low, it is working. It's a yes or no thing. Sounds like one or more effects may be slowing things down. Make sure you have the latest Red Giant versions, as older iterations weren't as efficient.

    If you install GPU-Z, or similar, you can monitor the usage of your video card. It does sound like something is not right.

    1st of all thank you;

    I have downloaded and installed it, and there is a ROG version so due to the fact i'm working with a GTX1080ti Strix i decided to use that one. I am using the standard ASUS tool too, which is reporting similar information, I want to see.

    Can't understand if Premiere is really working with CUDAs and how much or not, the temperature remains always around 45/51, so can't see a real stress.

    The GPU is not generally involved in exports unless they involve resizing, Lumetri,  Warp Stabilizer, or the other effects on the GPU accelerated effects list. It's not a long list.

    So perhaps you're not doing something to invoke that GPU. And also make sure that in your preferences you have Mercury acceleration set to CUDA.

    My export involves resizing, lumetri, warp stabilizer AND some other effects including Magic Bullet (I don't know if they are on the accelerated list or not)

    Of course, as I have written before, project preferences are set to CUDA.

    So, thank you for your answer but again seems that the investment in a GTX 1080 ti is a little bit wasted?

    It shouldn't be ... perhaps moving this to the Hardware forum will get more information from the better tech heads.
