Valve has released SteamOS 3.8, making its Linux-based operating system available for all hardware configurations. This move allows users to convert their current desktop computers into devices that offer a similar living-room PC experience to the upcoming Steam Machine.
The latest SteamOS version is available for download now, enabling users to create their own Steam Machine by installing it on compatible hardware. The process involves creating a bootable USB drive with the downloaded SteamOS image. Users on Windows can utilize the Rufus utility, while macOS and Linux users can employ Balena Etcher. It is important to note that Secure Boot must be disabled in the system's BIOS to proceed with the installation.
Upon booting into SteamOS for the first time, users will be presented with a desktop environment. The installation is initiated by navigating to the "Re-image Device" option. After the installation is complete, the machine will reboot.
Currently, SteamOS 3.8 features discrete AMD GPU support, which is still in beta as Valve continues to develop Nvidia compatibility, targeted for an official release in 2027. While Valve acknowledges that AMD GPU support is in beta, the extensive development for the Steam Machine and the Steam Deck suggests the OS should be stable enough for daily use. As a precautionary measure, users are advised to maintain a backup of their current operating system on a separate drive.
The official Steam Machine is scheduled to go on sale on June 30th, exclusively through Steam. Valve plans to implement a new ordering system designed to prevent issues that affected the launch of the Steam Controller.
