Valve’s FIRST public SteamOS build for Steam Frame is LIVE — and almost NOBODY can install it yet.
MIXED and GamingOnLinux report that SteamOS 0.3.0 for Steam Frame posted on September 17, three days after the headset’s September 14 launch. The notes are marked for ALL users. Purchase emails for the U.S. and Europe only START going out September 18, so the PATCH is mostly a preview of the software the first buyers will BOOT.
What 0.3.0 Actually Fixes
The general section is short and practical. Charging while the unit is off or sleeping is described as “SUBSTANTIALLY faster,” with no wattage numbers attached. The headset’s USB-C path still tops out at up to 45W on the spec sheet. Controller TRACKING improves while haptics are active. System STABILITY under high load gets attention. A “garbled audio” MICROPHONE bug is FIXED — Valve’s words, with no deeper root-cause note.
On the UX side, the per-app Motion Smoothing setting “Force Always-On” was being IGNORED; 0.3.0 restores it. Motion smoothing in pack-in Half-Life: Alyx is IMPROVED. A new VR Settings control dims the game when the DASHBOARD is visible. The Play Area page stops auto-showing BOUNDARY lines.
Developers Get Resolution Headroom
For STANDALONE titles, Valve CHANGED its Playable performance criteria to ALLOW any RESOLUTION — it was capped at 1440p before. Vulkan layer fixes aim at broader game COMPATIBILITY. Mesa graphics PERFORMANCE and overall OS responsiveness also move FORWARD. That is the ARM SteamOS track for Frame, SEPARATE from the SteamOS 3.8 / 3.9 builds Steam Deck owners see.
SteamVR Renames a Button. Shipping Still Sparse
MIXED notes a related PC-side drop: SteamVR beta 2.17.10 on September 15 fixed the same ignored Force Always-On path, turned Contrast Adaptive Sharpening off by default for Steam Link streaming, and addressed AMD Linux crashes. The OpenXR profile for Frame controllers, frame_controller_valve, now labels shoulder inputs as “shoulder” instead of “bumper” to match the OpenXR spec — with “bumper” still ACCEPTED for backwards COMPATIBILITY.
Japan’s KOMODO channel is still aimed at SEPTEMBER 24 shipping for first orders, per MIXED’s MoguLive cite. Until reservation buyers receive HARDWARE, 0.3.0 reads like Valve’s punch list for DAY-ONE software rather than a mass DOWNLOAD. The headset now has its own VERSIONED release notes — a quiet but CLEAR sign the Frame support LOOP has STARTED.
