M1 Mini shows using less than 30% of cpu

Resolve 17B8 Edit, rendering and Fusion processes that are complex enough to require me to wait only use less than 30% of CPU according to Activity Monitor. Is the Activity Monitor accurate? Any way to speed Resolve up to use 90% of the CPU? (if some must be reserved for system resources, otherwise prefer 100%)

Anyone have any suggestions?

The current M1 machines have a surprisingly powerful CPU but a pretty limited GPU, about half the power of a Radeon 580 in OpenCL tests. Resolve is relying heavily on the GPU, and if that is buys, the CPU sits half idle. Watch the GPU history too!
Their strength is decoding and encoding pretty much all GOP codecs in hardware – GPU working hard again. Feed it some RAW footage and you'll see how both CPU and GPI are getting very active.
