It's good and fast.

Don't use
--slices 4 --input-depth 10 --output-depth 10 --level-idc 51
x265 sets it automatically right. level 50 is sufficient for BD bitrates.

Maybe the --slices instruction is the cause of stuttering. ffmpeg had problems with it (lookahead).
I only make mkv and never had problems with --uhd-bd

ffmpeg64.exe -loglevel warning << info or verbose gives more information about decoding
Actually, if I recall correctly, I think I added the "--slices 4" in order to get rid of stuttering.

If you made an MKV it doesn't have to be UHD-BD compliant either... I can tell you that using "--uhd-bd" cause problems on my Sony player because it forces settings that cause stutter.
