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!

Thanks for the info. I also found this article: https://arstechnica.com/gaming/2023/04/nvidias-gamestream-is-dead-sunshine-and-moonlight-are-better-replacements/

It looks like I may need to look for another streaming option either way.

Wow, quite an update! I bought Quake II on Steam a long time ago and I like that this update was free - they could have squeezed a few dollars out of me, but I’m glad they didnt make me but it a second time.

(Or actually a third time since I still have the original I got in the nineties. Come to think about it, I dont remember if I actually bought it on Steam or if I just entered some code from the original CD.)
