I run Sunshine on Arch-KDE-Wayland with a 4070Ti and stream at 1440 to another PC running the same thing. I haven’t checked frame rates in a while but it seems to be running fine for me.

Does the Thor run Linux with the standard Moonlight client? If you haven’t looked yet, double check Moonlight’s settings and make sure the frame rate, resolution, and other settings look ok.

If you’re streaming a Steam game, also make sure Steam doesn’t have it’s recording enabled. I think Valve enabled it by default some time ago and that tanked my frame rate at the time. There’s a “Game Recording” section in Steam’s settings where you can turn it off.

Sunshine also has logs in the Troubleshooting section on its web client. Maybe see if there’s anything fishy in there too.

I don’t use Discord very much. Why do they have ID photos?
