SteamOS 3.7.5 Beta has just been released by Valve with a batch of valuable upgrades, marking an important step in the company's push to expand the handheld gaming ecosystem. From the very start of the update, SteamOS makes clear that it is no longer meant only for the Steam Deck and is also aimed at other handhelds such as the Rog Ally and Legion Go, opening a new era for cross-platform gaming.
SteamOS Beta Update: Support for Handhelds Beyond the Steam Deck and Better Performance
The biggest highlight of this SteamOS Beta Update is the addition of Handheld Support for two popular devices: Asus's Rog Ally and the Legion Go from Lenovo. This is the first time Valve has extended official support to handhelds other than the Steam Deck, letting owners of these two devices enjoy a smooth, fully featured SteamOS experience. Features such as power button detection and improved input handling for both the Rog Ally and Legion Go show that Valve is serious about building a unified software platform for the entire handheld gaming market.
Alongside that, the update upgrades the kernel to Linux 6.11 and brings the latest Arch Linux base and Mesa graphics drivers. This not only improves hardware compatibility but also delivers stronger performance. In particular, users with AMD chips will benefit greatly from CPU frequency management (P-State frequency scaling), which optimizes performance and saves battery when gaming on a handheld. In addition, the SteamOS Beta Update supports frame rate limiting and VRR (Variable Refresh Rate), keeping gameplay smooth on both the built-in and external displays.
A Better Desktop Experience, Improved Accessibility and Device Management
In Desktop mode, SteamOS updates to KDE Plasma 6.2.5 and begins moving to the modern Wayland platform, giving a smoother interface and better compatibility with newer apps. The Filelight app is now included by default, giving users a visual tool to manage and monitor disk space more easily.
On the accessibility front, the SteamOS Beta Update adds support for the Byowave Proteus controller, a modular gamepad designed with disabled users in mind. It is a meaningful step that underscores Valve's commitment to building an inclusive gaming environment for every kind of player. Bluetooth improvements also let Steam Deck LCD models “wake from sleep” using a standard Bluetooth controller, while the update adds battery level display for Bluetooth devices and improves connections with wireless headsets and microphones.
The overall experience also gets a boost, with smoother switching between gaming mode and desktop, surround sound support, and fixes for lingering issues such as slow shutdowns and desktop freezes in earlier versions. Some limitations remain, however, such as Bluetooth Low Energy controllers not yet supporting wake from sleep on the Steam Deck LCD, along with a few minor bugs because the update is still in beta.
Overview: SteamOS 3.7.5 Beta demonstrates Valve's long-term vision of building a multi-device handheld gaming platform that is no longer confined to the Steam Deck. The expansion of Handheld Support to the Rog Ally and Legion Go, together with a range of upgrades to performance, accessibility and the desktop experience, brings SteamOS closer to becoming the ideal gaming platform for every handheld. Although it is still in testing, this update is a positive sign for the gaming community, pointing to a more diverse and open future for the handheld gaming ecosystem.
