Intel OpenCL drivers could be required for some processors (Xeon, ...) to run some filters (KNLMeansCL, QTGMC, ...) - staxrip/staxrip GitHub Wiki

This has been reported by user vonH.

Xeon users may need some extra runtime to run KNLMeansCl and QTGMC.

  1. Go to Intel support site, search for "opencl runtimes" and download Intel® CPU Runtimes for OpenCL™ Applications for Windows 64.

The direct link to the search results (at the moment of writing this page) is https://software.intel.com/content/www/us/en/develop/tools/opencl-cpu-runtime.html?wapkw=opencl%20runtime

  1. Also you could need to replace the filter's dll inside Staxrip Download from here https://github.com/Khanattila/KNLMeansCL/releases/tag/v0.6.11 an older release more likely to work with Xeons, and put the x64 dll you find inside the archive in here \Staxrip\Apps\Plugins\Dual\KNLMeansCL (replacing the existing one)

  2. All other runtimes must be up-to-date as required for proper operation of Staxrip (check the App Manager in Staxrip)

IF you have a Ryzen processor untested on other cpus

  1. Simply download and install Intel® CPU Runtimes while ensuring other runtimes are up to date. QTGMC will work great on a ryzen processor with intels Open CL driver plus the included KNLMeansCL.dll.
