Valve has rolled out a preview build of SteamOS 3.8, bringing a range of updates aimed at improving performance across handhelds while laying the groundwork for future hardware.
The latest preview introduces early support for next-generation systems beyond the Steam Deck, signaling Valve’s broader push to expand its ecosystem. According to the release notes, the update includes initial groundwork for upcoming Steam Machine hardware, a category the company appears to be revisiting with modern specifications. SteamOS 3.8 also focuses heavily on refining the handheld experience. Valve has reduced controller input latency, improved compatibility with third-party handheld gaming devices, and delivered updated graphics drivers with performance and stability enhancements. A refreshed KDE desktop environment is included as well, alongside expanded support for a wider range of Intel and AMD system-on-chips.
While still in preview form, SteamOS 3.8 makes it clear that Valve is continuing to invest in both software and hardware, expanding beyond handheld gaming and setting the stage for a new generation of Steam-powered devices.
