Hi
My PC
CPU: AMD ryzen 5 5600G
MB: Asrock B550M-ITX/ac
I installed dualboot Win 10 and Linux mint 21 beta.
When I start win 10 and watch a 4K video from youtube, the CPU load is 0-1%.
When I start Linux and watch a 4K video from YouTube, the CPU load is 20-30%.
I also have a feeling that the 4K video is decoded by the CPU instead of the iGPU.
I tried different web browsers (Mozilla, Chromium, Google Chrome). HW acceleration is enabled.
