US EditionMajor SteamOS Update Adds Support for Steam Machine, Even More Third-Party Hardware
SteamOS 3.8 preview adds full Steam Machine support, improves Steam Deck power management and boosts compatibility with multiple third-party handhelds, Valve said.
- Valve released SteamOS 3.8.0 in preview, the first to support the upcoming Steam Machine living‑room PC, which Valve hopes to launch in the first half of the year.
- Valve began offering SteamOS to non‑Valve handhelds last May; only Lenovo is an official partner, so other installs require sideloading at users' risk, reflected by the large 'Non‑Deck' changelog section.
- SteamOS 3.8 adds Bluetooth Wake and desktop HDR/VRR, genuine hibernation for the Steam Deck LCD model, and improved video memory management for discrete GPU platforms like the Radeon RX 7600-caliber GPU.
- People running SteamOS 3.7 can access the 3.8 preview by switching the System Update Channel to 'Preview' in Settings, and Valve says the long-press power button feature works across devices with added battery and HDMI audio controls on Lenovo Legion Go handhelds.
- Desktop and TV improvements position SteamOS for broader roles, as Valve expects some will use the Steam Machine as a living‑room PC or traditional desktop, while wider adoption relies on user sideloading.
