I have noticed that the default media player on windows 10 can play 10bit hevc with hardware acceleration.
robert600 :
I can't say much about hardware acceleration except folks tell me it never works. I've used much slower dual core processors than yours to play HEVC files though. PotPlayer works much better for me than either of the 2 players you mention - download it and try - don't fiddle with the settings - just open it and load a file.
Thank you. I will try pot player.
