SteamOS 0.4 for Steam Frame has just been released for all users with the following changes:

Power:

  • Improved power efficiency and battery lifetime during both streaming and local gameplay, with gains of up to 12%. Note: Result vary depending on framerate and content.

  • Added user setting to control Presence Sensor Sensitivity (VR Settings -> Startup / Shutdown -> Presence Sensor). New “high sensitivity” option keeps displays on under a wider range of conditions, such as when using glasses spacers.

Streaming:

  • Improved color clarity during VR streaming (fixed headset chroma regression)

  • VR streaming reliability improvements, including fixes for “Error 17.” Note: On the PC, you must also opt into SteamVR 2.18.2 or later to reduce “Error 17” connection issues. At the time of this release, SteamVR 2.18.2 is available on the SteamVR [beta] branch.

  • Fixed steam frame wireless adapter connectivity issues that affected users in some countries.

  • Improved audio reliability while streaming

  • Fixed rare cases of other network interfaces causing disruption of wireless dongle connection.

  • Spectator view is now smoothed by default. Spectator view can be accessed on PC via Steam > Settings > Remote Play, or any device that supports Steam Link to preview what the Steam Frame user is seeing in headset.

  • Fixed the keyboard not appearing while streaming.

General

  • Fixed an issue that prevented controller bindings from loading for certain games, including Google Earth VR and Thumper.

  • Improved focus behavior when interacting with grab/resize handles

  • Improved focus handling and gamepad navigation in the dashboard.

  • Fixed a case of dashboard panels flickering.

  • Fixed “Return to Gaming mode” when starting up directly into Desktop mode.

  • Added option to disable spectator view smoothing under VR Settings > Developer (in headset).

  • Fixed an issue where the dashboard would recenter unnecessarily for some users.

  • Updated embedded browser (CEF) with crash fixes and Linux H.264 detection fixes.

  • Miscellaneous performance and stability improvements.

  • Improved tooltip sort ordering

Audio:

  • Audio: downmix and binaural rendering now have matching volume across all formats.

Accessibility

  • Added accessibility option for users who want to limit eye tracking to a single eye. VR Settings -> General -> Track Dominant Eye Only. (requires enabling “show advanced settings”)

  • Users can now specify their Dominant Eye in VR Settings. This controls which eye is used for spectator view, screenshots, etc.
