SteamOS 0.5.7 Beta for Steam Frame adds WebXR, SteamVR 2.19.1, controller fixes

Valve has shipped SteamOS 0.5.7 Beta for the Steam Frame, its standalone VR headset, marking a notable update to the device's firmware since launch. The release upgrades the underlying SteamVR runtime to version 2.19.1 and introduces WebXR support in Chromium 157 and later versions, enabling browser-based virtual reality experiences without dedicated applications. Several user-reported issues receive fixes, including corrected battery level display at 0% for Frame Controllers, improved vibration filtering for pose prediction, and resolved audio dropouts with USB or Bluetooth speakers when microphone access is requested.

The update also adjusts foveated sharpening to operate independently of eye tracking, removes Advanced Supersampling support on this hardware, and adds microphone controls for echo cancellation and noise suppression that require the current Steam Client Beta. Default controller bindings now cover Chromalab, Batman Arkham, and Doom VFR. Users must opt into the Beta channel via Settings to receive the update.

Steam Frame VR stack and SteamOS changes

• SteamVR runtime: Updated to version 2.19.1 with improved vibration filtering for pose prediction to address tracking inconsistencies on some units.
• WebXR support: Enabled in Chromium 157 and newer, allowing browser-based VR content to run on the Steam Frame without native application installation.
• Foveated rendering: Sharpening is now decoupled from eye tracking; previously disabled when eye tracking was off, it now defaults to a centered profile.
• Audio subsystem: Fixed microphone-access-triggered audio failures with USB and Bluetooth speakers; added toggles for echo cancellation and noise suppression requiring Steam Client Beta.
• Controller firmware: Battery indicator now correctly displays 0% instead of failing to report; new default bindings added for Chromalab, Batman Arkham, and Doom VFR.

Why it matters

This update signals Valve's continued investment in the Steam Frame as a standalone Linux-based VR platform, expanding its capability beyond SteamVR-native apps into standards-based WebXR content that could broaden developer reach. The specific fixes for audio routing, controller battery reporting, and pose prediction address early-adopter pain points that had generated user complaints, while the removal of Advanced Supersampling suggests Valve is refining the rendering pipeline for the device's mobile-class GPU constraints.
