Valve's Steam Frame 0.4.3 Beta Boosts Battery Life by 12%
Valve released SteamOS 0.4.3 beta for Steam Frame, adding up to 12% better battery life, single-eye tracking, and fixes for controller bindings and Error 17.
Valve has released the 0.4.3 beta update for SteamOS on the Steam Frame, bringing a set of improvements and fixes to the VR headset. The headline change is a boost to power efficiency that extends battery lifetime by up to 12% during both streaming and local gameplay.
The update also adds an accessibility option that lets users limit eye tracking to a single eye. Controller bindings that previously failed to load for certain games—including Google Earth VR and Thumper—now work correctly. Valve says focus behavior when interacting with grab and resize handles has been improved as well.
VR streaming reliability gets further attention in this beta, with additional fixes for Error 17. The update also resolves wireless adapter connectivity issues that affected Steam Frame users in some countries.
As reported by pcgamer.com, the 0.4.3 beta follows recent work on the Steam Frame's charging system, which now supports fast charging even when the headset is powered off. SteamOS for Steam Frame is a new Arch-based Linux distribution built for virtual reality and Arm-based processors, specifically the Qualcomm Snapdragon 8 Gen 3.
In related hardware rumors, a recent report suggests the Steam Deck 2 will use an AMD chip. Valve has not commented on that speculation.
