Valve’s SteamOS Beta Adds Initial Gamepad Support for More Third‑Party Handhelds

The 3.8.25 beta signals a push to broaden SteamOS to Intel and ARM handhelds through cautious, incremental releases.

Overview

  • SteamOS 3.8.25 Beta, which rolled out Monday, August 10, adds initial gamepad support for the MSI Claw 8 EX AI+, the AYANEO Pocket S2, and the Konkr FIT.
  • Valve also lists improved support for other MSI and OneXPlayer models and updated gamepad handling for the OneXPlayer Apex.
  • The beta includes system-level changes such as preliminary wireless support for the Steam Frame VR adapter, a revised Linux driver for the new Steam Controller, and Steam Machine firmware that fixes a rare CPU slowdown after waking from sleep.
  • All changes are marked as beta or initial, so users should expect incomplete functionality and possible issues with Windows-only anti-cheat that can block some multiplayer games.
  • Only a few devices ship with SteamOS preinstalled, so these incremental updates aim to make the OS a viable install option on more third-party handhelds and could lead to more wider compatibility over time.
