Valve has taken a significant step toward the upcoming release of the Steam Frame. The latest SteamOS 3.8.25 Beta update introduces preliminary support for the Steam Frame Wireless Adapter, signaling that the hardware is nearing its market debut. Given that Valve historically adds support for new devices in the weeks leading up to their shipping date, users can expect the VR headset to arrive by the end of August.
The update includes more than just preparations for the new headset. It brings functional improvements to the Steam Controller experience by adding support for the 2026 model to the system driver. This change allows for native controller application use even when the Steam client is not currently running. Additionally, the update provides a fix for the Steam Controller Wireless Adapter from 2015, which now supports device wake-up functionality.
Beyond hardware-specific support, the patch addresses technical stability for the broader Steam ecosystem. Users of the desktop mode will benefit from fixes for HDMI display lockups and improved hotplug detection. The update also tackles audio dropouts over HDMI and resolves Wi-Fi connectivity problems that impacted specific adapters.
Valve continues to expand support for non-Valve handheld devices within SteamOS. The new firmware includes adjustments for the MSI Claw series, the OneXPlayer line, and the AYANEO Pocket S2. These changes ensure that gamepad support is active for a wider range of hardware configurations. The system also moved to the Linux kernel version 6.18.42 to provide improved security and general performance for all supported platforms.
