Stadia - Bad Video Quality despite HW-Decoding

Sorry for another Stadia Streaming thread.
I could not find anyhting about my specific topic.

Configuration

  • NVIDIA Graphics card
  • Chrome or Chromium browser started by: chromium --disable-frame-rate-limit --disable-gpu-vsync --use-gl=desktop --enable-features=VaapiVideoDecoder
  • Chrome-flags set and packages installed as far as im able to manage (taken from several documentations and recommendations which can be found)
  • HW acceleration working
  • latency = 22ms / decoding = 2ms

Problem

Gaming/Responsiveness is OK i think.
I don’t have a comparison to another system.

The graphics are NOT GOOD at all!
I don’t have enough knowledge to find out where this comes from.

Question

I just want to know if there is now something obvious i dont see or if i did everything i can, HW decoding is working and thats just the best possible result which can be achieved with my hardware(-combination).

Thanks in advance
