SteamOS 3.8.25 Beta: Steam Machine Firmware, Handheld Support, and Steam Frame Drivers
Valve has released SteamOS 3.8.25 Beta, bringing Steam Machine Firmware 108 with critical sleep and CPU performance fixes alongside expanded gamepad support for the MSI Claw, OneXPlayer, AYANEO Pocket S2, and Konkr FIT. The update also delivers preliminary drivers for the upcoming Steam Frame Wireless Adapter, resolves a confusing speaker dropout bug on Steam Deck OLED units, and patches HDMI and Bluetooth audio issues. While desktop mode users will appreciate fixes for app persistence and TV Game Mode flashing, the beta currently carries a known performance regression when using FSR that stable release 3.8.16 already resolved. Until that composition bug is patched, most owners should hold off unless they specifically need the Steam Machine or third-party handheld improvements.

However, users should be cautious as the beta version has a known performance regression with FSR that was resolved in the previous stable release, prompting most users to stick with version 3.8.16 unless they require specific improvements. Overall, the update reflects Valve's ongoing commitment to enhance the Steam ecosystem while addressing issues across both Valve and third-party hardware
