видеокадры заметно обновляются при воспроизведении видеоклипов или YouTube на Ubuntu 20.04

My computer comes with strong hardware: AMD Ryzen 3900X; 64G memory; Navdia RTX 2080 Super. Ubuntu 20.04 was installed.

However when I watch youtube videos or test a 1080p mkv format video, I can observe video flames refreshing at noticeable speed, meaning it's slow! This should never happen considering my hardware!

My guess was that no proper driver installed, but running "ubuntu-drivers devices" seems showing the driver installed.

My monitor support 4K (ViewSonic XG2700-4K).

Motherboard is: ASUS AM4 TUF Gaming X570-Plus (Wi-Fi)

Here are some preliminary diagnosis I performed:

  • sudo dmidecode -s bios-version , return: 1407
  • free -h
 total used free shared buff/cache available 

Mem: 62Gi 5.8Gi 33Gi 809Mi 23Gi 55Gi 
Своп: 2.0Gi 0B 2.0Gi
  • sysctl vm.swappiness

vm.swappiness = 60

Кто-нибудь знает, каков основной курс для этой проблемы или какие конфигурации мы можем сделать в Ubuntu? Я ожидал супер производительности при просмотре видео с высоким разрешением или во время игр.
