The SteamOS 3.7 update (officially version 3.7.8) marks a notable expansion in Valve’s approach to its Linux-based gaming operating system. This update extends official support beyond the Steam Deck by incorporating compatibility with generic AMD-based PCs as well as various AMD-powered handheld devices. Detailed installation instructions are now provided for devices such as the original Lenovo Legion Go and the ROG Ally, requiring users to disable Secure Boot and prepare a recovery image using tools like Rufus or Balena Etcher. These measures standardize the deployment process for hardware that fits the AMD criteria, eliminating the need for community-maintained distributions to achieve a SteamOS-like experience.

In addition to the broadened hardware support, the update includes several system-level enhancements designed to improve overall performance and user experience. The underlying software now utilizes an updated Arch Linux base and a newer Linux kernel (version 6.11), alongside revisions to the KDE Plasma interface in desktop mode (version 6.2.5) and updated Mesa graphics drivers. Various bug fixes and performance optimizations have also been implemented, aiming to enhance stability and compatibility across a wider range of devices. Collectively, these technical improvements underscore Valve’s intent to refine and extend the usability of SteamOS across AMD-powered PCs and handheld platforms.
