Thursday, June 18th 2026 SteamOS 3.8 Stable Release: Wider Handheld Support and Improvements for DIY Steam Machines by Cpt.Jank Today, 12:56 Discuss (1 ) Despite the Valve Steam Machine being right around the corner, there has been a lot of interest from gamers who want to run SteamOS on custom gaming desktops or DIY Steam Machine console builds, while others may be looking to extract as much of the Steam Deck experience out of something like a used Lenovo Legion Go after the recent Steam Deck price increases. Fortunately, the latest SteamOS release, version 3.8, has officially landed in the stable release channel with a host of compatibility, performance, and usability upgrades. First and foremost, SteamOS 3.8 brings initial support for the upcoming Steam Machine and improvements to the desktop mode for those who want to use the Steam Machine as a PC-console hybrid. This is aside from a host of bug fixes for both the OS and certain game bugs and general improvements to the overall level of polish of the OS. SteamOS 3.8 updates both the Arch Linux base and the KDE Plasma desktop mode to KDE 6.4.3 and switches to the Wayland display protocol by default. The update also improves VRR frame pacing and adds support for HDMI Variable Refresh Rate thanks to AMD's recent efforts to bring HDMI 2.1 support to Linux. The OS now also supports the LAVD CPU scheduler if manually enabled via the command steamosctl set-cpu-scheduler lavd. SteamOS 3.8 also updates the graphics driver and fixes performance discrepancies between game mode and desktop mode, specifically addressing performance regressions in desktop mode. It also re-enables Bluetooth wake from sleep on Steam Deck LCD models. There are also improvements to game capture in game mode, as well as support for HDR, VRR, and per-display scale factor on external displays in desktop mode. Critically for desktop builds, SteamOS 3.8 also significantly improves video memory management on systems with discrete GPUs and support for recent Intel and AMD platforms. The update also adds or improves overall platform and controller support for a host of gaming handhelds, including:OneXPlayer F1 series, Apex and X1GPD Win 5GPD Win MiniAnbernic Win600Lenovo Legion Go 2Upcoming Intel Arc handheldsMSI Claw A1M, 7AI+, 8 AI+ A2VM, A8 BZ2EM Source: SteamOS Related Tags: Handheld KDE Plasma Legion Go 2 Lenovo Linux OneXPlayer OS Stable Steam Steam Deck Steam Machine SteamOS Wayland May 28th 2026 Leaker Hints at Astronomical Steam Machine Pricing (74) Apr 29th 2026 Linux now Officially Available for PlayStation 5 (19) Dec 15th 2025 Microsoft Copilot AI Comes to LG TVs, and Can't Be Deleted (144) Apr 3rd 2026 Steam Deck 2 Ditches Semi-Custom APU for Off-the-Shelf AMD Silicon, Eyes 2028 Launch (45) Nov 13th 2025 Valve Announces Steam Machine, Steam Frame, and Steam Controller (204) Nov 17th 2025 Valve Claims Steam Machine Outperforms 70% of Current Gaming PCs (133) Nov 29th 2025 Valve Steam Machine May Cost Less Than Anticipated (118) Dec 9th 2025 Valve Trying to Unblock Open-Source HDMI 2.1 Support on Steam Machine (37) Feb 22nd 2026 AMD Seemingly Stops Driver Updates for Ryzen Z1 Extreme Processor (119) May 30th 2026 SteamOS Update Adds Support for Slew of Gaming Handhelds and VRR on HDMI (7) Add your own 1 on SteamOS 3.8 Stable Release: Wider Handheld Support and Improvements for DIY Steam Machines #1 simlariver Awesome !
