That is not for desktops. I would assume they meant a proper steamOS desktop release. We haven’t seen one in many years and the previous one is basically useless for most people.

Many of us have been waiting for a proper release for a LONG time. Bazzite is nice but I want to see what valve does next.

my guess is it will be mostly the same as for the SteamDeck but with

- Game Mode becoming getting a not Steam Deck specific desktop version, which I would love to see, e.g. last time I installed Bazzite+Steam Game mode, the Game Mode will default to 1080p even if your GPU can render 4k ...(easy to fix in the options menu, tho. But not very convenient.).

- slightly different defaults, tweaks, builds (e.g. AFIK not to long ago if you tried to put SteamOS on a desktop with RDNA3 graphics it didn't work. But they seem to more or less just use a standard linux graphic stack, so it's probably was just something on the line of "as it's not expected the parts needed for RDNA3 wheren't compiled in/shipped in the SteamOS for SteamDeck image)

There's nothing stopping you from installing it on a desktop with the right hardware.

I have a Ryzen 5 5600 and a 7600 xt in an sff pc, installed steamos directly from the recovery image. It supports the GPU, controllers, even the super fast sleep/wake.
