Valve has released SteamOS 3.8.25 Beta, adding preliminary support for the Steam Frame Wireless Adapter alongside crucial performance fixes and third-party handheld compatibility improvements, according to patch notes published on the Steam Community.
SteamOS Beta Update Hints at Steam Frame Release Timeline
The newly added support for the Steam Frame Wireless Adapter suggests Valve’s upcoming virtual reality headset is nearing its public debut, according to coverage by Steam Deck HQ. Historical update patterns point toward a late-summer rollout. Valve introduced preliminary support for the Steam Machine roughly three weeks prior to that hardware’s official launch. If the company maintains a parallel schedule for its VR hardware, the Steam Frame could arrive by the end of August, just ahead of the close of meteorological summer.
Did you know? Valve added a dedicated “Great on Steam Frame” category to the Steam Store featuring compatible applications like Portal 2 and The Lab, according to reporting by Notebookcheck.
Steam Machine Firmware 108 and System Stability Fixes
According to the Steam Community release notes, the SteamOS update bundles Steam Machine Firmware 108 to address persistent power management bugs. The updated firmware resolves a glitch that occasionally caused systems to wake up immediately after entering sleep mode. It also patches a rare issue that previously degraded CPU performance until a system reboot occurred following a wake cycle.
General system improvements target common hardware friction points. The software adds support for waking devices using the 2015 Steam Controller Wireless Adapter and updates the built-in hid_steam driver for the 2026 Steam Controller. This driver update lets users operate the controller with native applications even when the Steam client is not running. Other fixes resolve Desktop Mode lockups caused by hotplugging HDMI displays, eliminate unnecessary boot logo flashing on TVs utilizing HDMI “Game Mode,” and correct Wi-Fi connection drops.
Expanded Support for Third-Party Handhelds
Non-Valve hardware receives notable attention in the latest beta build. Valve improved overall compatibility for MSI Claw and OneXPlayer device variants. Furthermore, the update introduces initial gamepad support for the MSI Claw 8 EX AI+, the Konkr FIT, and the AYANEO Pocket S2. Owners of the OneXPlayer Apex will also find updated gamepad support tied to new device firmware, according to Steam Community documentation.

Audio stability gets a boost via fixes for HDMI audio dropouts across specific game and television combinations, alongside improved HDMI hotplug reliability. Bluetooth users can now select an option to prefer lower-latency audio codecs. On the developer side, Valve bumped the Linux kernel to version 6.18.42.
