I’ll just reply to myself. According to the documentation, the combination of https://github.com/LizardByte/Sunshine and https://github.com/moonlight-stream seems to be a viable alternative that should work under Linux. (I have only tested them on Windows so far).
If anyone are looking for an alternative of streaming via Steam, this is something you might be interested in.
Cheers!
Sure, but I’m no expert - I’m very much in “learning mode”.
Sunshine is a drop-in replacement of Nvidias GameStream server which (under windows) can be enabled in the GeForce Experience application. This is run on the gaming computer and captures the screen and audio.
Moonlight is the replacement on the client. In my case, I run this on the small fanless PC in the TV room where I want to play the games (and sometimes on my Android phone just for fun).
Once both programs are running on the same network (a high speed wired connection is recommended even if I run it over wifi), the Moonlight client detects the Sunshine server and if you click on it, you get a four digit code that you must enter into the Sunshine config interface (web based) to authorize the pairing (this only needs to be done once).
Then - just like steam link - the client sends the keyboard, mouse and gamepad inputs back to the Sunshine server, while audio and video are sent to the client. Everything pretty much works out of the box except gamepads which required an additional driver on the server.
It seems that both Sunshine and Moonbeam supports even non-Nvidia GPU.
I’ve been using Moonlight for years but I’m still working out a few minor kinks in Sunshine. It works as good as the original server on Quake II (2023 remaster) and Red Dead Redemption 2, but under Quake II RTX the framerate is stated as 60 but looks more like 30 on the client side.
