Why --pools "5"? Are you running on a NUMA system? I would think that explicitly setting --frame-threads would control quality and perf better. If you're running on a NUMA system, you can then set --pools "+,-" or whatever.
The number of frame threads is what impacts quality in multithreaded encoding, so better to set that directly and let x265 figure out how many cores and threads it can productively use for that encode.
using --pool 5 would map to --frame-threads 3.
Or is this about something else entirely?
