Open GL on Premiere with a RX 570

[Hon Tho]

I come across the Mercury software render only thing in the project settings which is a bummer... and really wanted my RX 570 8GB to do the work... and this worked for me.

Installed latest drivers from the Radeon site with the automatic installer software. A couple reboots later and it was installed.

Also opened the registry editor at Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Khronos\OpenCL\Vendors 

and changed IntelOpenCL64.dll from 0 to 1

On this older but still good working rig:

• I7-4770K
• 16GB
• RX 570
• Crucial BX500 1TB SSD
• WIN 10

Hope this helps someone else.

Those actions alone help with the conflict between the integrated Intel graphics and a discrete Radeon GPU, both of which use OpenCL in Windows. If you have a newer system, and have enabled QuickSync for hardware-accelerated decoding, then only the Intel graphics will be used for rendering unless you perform that registry tweak. The discrete Radeon GPU will sit mostly idle.

Users with QuickSync enabled but with a discrete Nvidia GPU have it much simpler: Since Nvidia artificially restricted OpenCL support to version 1.2 (below the version 2.0 that Premiere Pro requires), if OpenCL is selected for the renderer, then only the Intel graphics will be used. To use the Nvidia GPU for rendering, CUDA (not OpenCL) must be selected for the renderer.
