Windows 10 running Darktable not using PC at full capacity

Hi’ Everyone

On my pc NVIDIA GPU is no. 0 and Intel GPU is no. 1.

It turns out that the setting opencl_device_priority = !1,“star”/!1,“star”/!1,“star”/!1,“star” works very well in respect to directing all graphic work to NVIDIA.

How do I determine if this is the best setting in respect to darktable overall performance on windows? Good ideas will be appreciated.
