@mischievoustomato @RustyCrab @phnt it's going to be a year to 2 years imo before we see a desktop steam os release. The red hat open source nova drivers for nvidia rtx 2k and beyond cards aren't passed their infancy.
We aren't going to see anything happen until they're ready as Valve isn't going to package nvidia's linux graphics drivers in their SteamOS image.
The best you'll get for desktop steamos from valve is them releasing a steambox or you hamfisting the steam os recovery image onto an all AMD pc build.
