OpenCL option missing with GTX1070

Hello,

in order to use RedGiant Denoiser III at reasonable processing speeds, I have to enable OpenCL in Premiere. Unfortunately, the only options I have are software acceleration and CUDA, but the OpenCL option is missing.

Checking GPU-Z shows me that OpenCL is enabled in the graphics card itself.

I already updated (clean installed) my gpu drivers over GeForce Experience, but to no avail.

Any ideas on why it might not be shown?

Thanks,

Luca

Specs:

Ryzen 7 1700

GTX1070 8G

16GB

Samsung 860 Evo

Win10

Sorry, but Adobe has permanently disabled OpenCL in MPE in all versions of Premiere Pro to date on Windows systems that use only NVIDIA GPUs. The only way to enable OpenCL accelerated rendering on an AMD CPU-based Windows PC is to switch from an NVIDIA GPU (such as your GeForce GTX 1070) to an AMD GPU (such as a Radeon RX 580).

That policy dates back to the days when Kepler was the newest NVIDIA GPU architecture that was being sold through resellers, and Fermi and Tesla GPU architectures were still in wide use. All of those architectures have historically had very poor OpenCL performance compared to their corresponding ATi / AMD counterparts.

This quite frustrating news.  Why would Adobe limit itself to lower tier GPU's?  I specifically bought a Nvidia GPU because I wanted a more capable processor.

    They assume if you're using an Nvidia card, you'll use CUDA acceleration.
