PMS on Ubuntu 21.04 - Intel i5-10500 CPU streaming problem

Hello, I bought new machine with Inte i5-10500 CPU, M.2 SSD and Intel UHD 630. I installed fresh new installation of Ubuntu 21.04 server including libopencl and latest intel runtime.

When I turn on HW transcoding the stream slow down/stuck/freezes. Im playing 4k HEVC movie on Apple TV Plex client (only one stream, no other streams playing in the same time).

Should I install/change any settings? Any suggestions, please? thanks a lot, David
