You have to disable the OpenCL renderer for the Intel iGPU, you make this from Registry Navigate to the following locations : Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Khronos\OpenCL\Vendors\ Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Khronos\OpenCL\Vendors\ There you will find the Dword for the IntelOpenCL64.dll driver .. you either modify the value to 1 Which means False (disabled) and not use it, or do like me and delete the entry (technically deny the iGPU to ever be used as an OpenCL device) and restart your PC!
