Valve released SteamOS 3.8, bringing a major operating system update to its gaming ecosystem. The release introduces a new Linux kernel and updates to the desktop environment for better stability. This update also adds initial firmware support for upcoming Steam Machine hardware.
Major OS update improves handheld controller latency and adds Steam Machine firmware
The update targets Steam Deck owners and users of third-party handhelds. It includes new BIOS versions for both the Steam Deck LCD and OLED models. The Steam Deck LCD receives BIOS v133, while the OLED model gets BIOS v114.
- Linux Kernel Version: 6.16
- Desktop Environment: KDE Plasma 6.4.3
- Steam Deck LCD BIOS: v133
- Steam Deck OLED BIOS: v114
- Controller Input Latency: 100-500us
Valve significantly reduced controller input latency on handheld devices. The update cuts latency from 5 to 8 milliseconds down to 100 to 500 microseconds. The company also improved VRR frame pacing to enhance visual smoothness during gameplay.
The update addresses Bluetooth wake issues for the Steam Deck LCD and fixes WiFi performance problems. It also adds compatibility improvements for devices like the OneXPlayer X1, Legion Go 2, and MSI Claw. These changes aim to provide a more consistent experience across different hardware configurations.
When we covered the last steamos update, several of the same balance and stability themes came up. The current release continues that trend by focusing on foundational improvements rather than new features. Users can now expect faster OS updates on high-speed connections due to backend changes in the update mechanism.
