[HELP] how to using x265 in Hybrid correctly?

[Selur]

i heard about that NVENC is using for NVIDIA card, and it encode much faster, but quality is not as perfect as CPU

Yes, the fine detail preservation is usually better with software (CPU) based encodings, but in your source there are no details to preserve so using software encoding and trying to tweak it simply seems like a waste of time.
