Throubleshooting stuttering playback with HW transcoding

[Graxo 0]

Hi,

Im running a virtual machine on Proxmox with the following specs:

CPU: 12x vCPU (1 Socket,  AMD Ryzen 5 4600G with Radeon Graphics)
RAM: 8 GB (Crucial DDR4 3200MHz)
Storage: 30TB of a 65TB ZFS pool configured in Proxmox
Network: 4x 2.5gb nics configured in a LACP (802.3ad)
GPU: PCI passthrough a Nvidia Tesla P4
OS: CentOS Stream 9

I run Emby in Docker, this is my docker-compose.yaml for it:

  emby:
    container_name: emby
    image: emby/embyserver:latest
    environment:
      - TZ=Europe/Amsterdam
      - UID=0
      - GID=0
    network_mode: bridge
    ports:
      - 8096:8096
    volumes:
      - /docker-data/dl-group/emby/config:/config
      - <data volumes>
    restart: unless-stopped
    # This is how GPU support is configured with recent docker/docker compose:
    deploy:
      resources:
        reservations:
          devices:
            - driver: nvidia
              count: 1
              capabilities: [gpu]

Everything seems to work fine with the HW transcoding, there is green icon when playing something in the Dashboard.

When i play something, its stuttering, i checked multiple video files but they all have the same issue.
Is there someone with experience on throubleshooting this? What else can i try? Or take a look at?

Kind regrads,
