When encoding video, Hybrid only uses ~50% of the CPU resources. I do not have any thread restrictions set as far as I know. I'm using a Ryzen 9 5900X.
I am going from UHD HDR to FHD SDR x265 10bit. The only vapoursynth filter being applied is DG HDRtoSDR.

I took Selur's advice of increasing the complexity of the encode by raising --rd from 3 to 5, along with some other adjustments, but all it did was reduce the fps while still using ~50% CPU.
I also noticed on startup that Config -> Internals -> Handling "FFmpeg/MEencoder threads" incorrectly identified the core count as 24 (it's 12 cores, 24 threads) and the default value was set at 8. I increased the value to 24, but CPU still remained at ~50%.

Hybrid is also not using maximum GPU for DGDecNV.
Debug is attached.
Encode settings are:
