Valve continues to expand SteamOS support for third-party handhelds, moving beyond its historical focus on AMD-powered hardware to target Intel-based devices. The SteamOS 3.8.25 beta specifically supports the MSI Claw 8 AI+ utilizing Lunar Lake architecture, alongside devices like the Ayaneo Pocket S2, Konkr Fit, and OneXPlayer Apex. Testing shows demanding titles such as ‘Cyberpunk 2077’ and ‘Forza Horizon 6’ can run stably at a 15-watt power draw. This expansion positions SteamOS as a potential general-purpose handheld operating system, challenging the Windows-centric market. Recent software iterations have focused on hardware stability and desktop environment enhancements. The SteamOS 3.8.26 Beta addressed performance regressions involving FSR-enabled composition, WiFi connectivity on the MSI Claw A1M, battery display errors on Lenovo Legion Go models, and system freezes related to SD card usage on the MSI Claw. It also resolved Bluetooth instability with the Nintendo Switch Pro (v1) controller and a bug affecting Unreal Engine 5 VR games. ~~Moving into~~ In the 3.9.0 preview phase, Valve ~~has~~ introduced a major refresh to the desktop environment by upgrading KDE Plasma to version 6.7.3 and the Linux kernel to version 7.2. This update brings enhanced search capabilities via Krunner, a new clipboard pinning feature, and expanded support for drawing tablets. Technical improvements include HDMI 2.1 support, improved Wi-Fi compatibility via the wpa_supplicant backend, and preliminary support for hibernation, though the latter is not yet available in Gaming Mode. Further refinements arrived with SteamOS 3.8.28, which introduced a new Mesa graphics driver to improve raytracing performance and VRAM management. This update specifically targets stability issues when devices wake from standby, particularly for discrete AMD graphics cards. Additionally, Valve released Firmware 108 for the Steam Machine to address CPU performance drops and sleep-mode bugs.
