Again… SteamOS is just an immutable version of Arch Linux. That’s what they are talking about in the article when they talk about turning off “read-only” mode. Being immutable makes it less likely to break/more stable, but doesn’t “fine-tune” it for gaming.
Saying it’s “fine-tuned” for gaming takes away from what is actually doing the heavy lifting for gaming on linux, which is Proton. One could argue Proton is “fine-tuned” WINE, but SteamOS is not “fine-tuned” for gaming.
That is not the smoking gun you think it is.
