@foxyshadis. Thanks. Do you have a suggestion for how many maximal --bframes and & --refs I should set in x265 to keep a generally high compatibility for GPU-decoding (main10@L5.0)? I've read that when encoding cartoon/anime, maximal --bframes and & --refs should be set for high compression.
I guess that maximal --refs depends on the resolution, like for H264-encoders?!
Are the x265-levels the same as x264-levels when it comes to --refs?
This page calculates maximal reference-frames for a certain H264-level,

UPDATE: I saw that my laptop's graphics-chip is a Nvidia GeForce 840M GM108, so only support for main, not main10?! But I've played main10 (x265-video that I've encoded with --main10 in 10-bits), my MPC-HC says that a x265 main10-videoclip I have is "Playing [H/W], maybe it's slow decoding of main10?!
UPDATE2: OH, sorry, I forgot to mention: maybe I'm wrong about my laptop with a Nvidia GeForce 840M GM108. Maybe my MPC-HC uses my Intel CPU graphics in that laptop to GPU-decode H.265/HEVC-video?
