Apologies for replying to myself, I realized I sent the last message without important version/troubleshooting information:

Platform: Windows 10 Pro, 10.0.19045 Build 19045
DigiKam version 8.8.0

In DigiKam, Help > Components Information states that OpenCL Availability is "No"

I noticed that the ToolTip when enabling OpenCL states, "This option is still experimental and requires that certain environment variables are set manually." I checked the docs but could not find a reference to these environment variables. I found this note online (https://discuss.pixls.us/t/opencl-not-showing-in-digikam/49711/4) suggesting that adding "OPENCV_OPENCL_DEVICE=NVIDIA:GPU:" might correct the issue.

I added a system-wide environment variable (via Control Panel > System Properties > Environment Variables > System Variables) of "OPENCV_OPENCL_DEVICE" ="NVIDIA:GPU:" , validated it was set in the command line, then restarted DigiKam. Still no change.

Any further troubleshooting I should perform?
