Even gamers nexus’ Steve today said that they’re about to start doing Linux games performance testing soon. It’s happening, y’all, the year of the Linux desktop is upon us. ᕕ(ᐛ)ᕗ
Edit: just wanted to clarify that Steve from GN didn’t precisely say they’re starting to test soon, he said they will start WHEN the steam OS releases and is adopted. Sorry about that.
You should give Bazzite a go on your desktop, it’s very similar to SteamOS and the desktop experience has been great for me. I didn’t have a Steam Deck and transitioned to it, and the smoothness convinced me to get a Lenovo Legion Go and install Bazzite straight OOTB.
