Performance using older moonlight

[Tmarinus]

I get that is is not fully apollo question but only partially related.
I am having some issues with updating moonlight client. I am currently running moonlight flatpak client (linux mint 21) version 4.3.1 running over cable to other computer (Host: 10400f + 3070, windows 10. Client linux mint 21 amd 2200g, 1gb wired lan, HVEC) this gives me quite smooth experience (average rendering time including vsync) of around 0.4ms which is nice.

When i update moonlight to 6.0.1 through app.image / flatpak / snap I get a 8ms latency. This is both the case when I use sunshine or geforce as client. When I use Apollo and moonlight 6.0.1 I get 4ms (improvement but still not as close as old client). I am unable to use moonlight 4.3.1 and appolo host, this just gives a black screen.

Would anyone know why newer moonlight can cause this 20x or 10x decrease in performance? Am I hunting a ghost and did old moonlight just never report correct ms?

I tried getting help in sunshine forums etc but didnt get any answers. Since I still spot something similar in Apollo I hope it is okay that I ask here.

Much thanks for the help,
Tycho

If you don't feel anything different, then you're probably hunting for a ghost.

Moonlight always had problems reporting the correct decoding latency and they're inconsistent across clients on different platforms. The best way to test it is record your physical screen and streamed display with a high speed camera.
