SteamOS Runs on ASUS ROG Ally, Complete Ecosystem Support Coming Soon
We are inching closer to Valve releasing an official, unmodified version of SteamOS for third-party handhelds and PCs, a significant push to broaden its gaming ecosystem beyond the Steam Deck. While the final build remains pending, tech reviewer The Phawx recently showcased an unofficial SteamOS 3.8 installation on the ASUS ROG Ally (2023), offering a glimpse into its current capabilities—and limitations. Running on Ally's Ryzen Z1 Extreme chip, SteamOS already delivers solid performance in titles like Batman: Arkham Knight (73.3 FPS) and Horizon Zero Dawn (55.9 FPS) at 720p. However, challenges persist: hardware-specific features like Ally's VRR (Variable Refresh Rate) work, but its TDP controls and dedicated buttons remain non-functional. In Cyberpunk 2077, the Steam Deck narrowly outperformed the Ally (47.8 vs. 45.8 FPS), a result attributed to Valve's bespoke optimizations for its own hardware. The lack of TDP adjustment also led to inefficiencies, with some games defaulting to 20 W power draws.
Valve's upcoming "Powered by SteamOS" branding initiative aims to standardize third-party integrations, requiring partners to use official system images and launch directly into SteamOS. Early collaborations, like Lenovo's CES-announced Legion Go S, also contribute to this goal. Meanwhile, updates like SteamOS 3.6.19 have expanded support for devices such as the ROG Ally and third-party controllers, suggesting broader compatibility ahead. Valve's expansion could position SteamOS as a rival to Windows in the portable PC space, leveraging its gaming-first interface and growing developer support. While The Phawx's demo has shown SteamOS's potential, Valve's official release—expected to resolve current hardware quirks—will determine its viability for partners. As competition heats up, SteamOS's success may hinge on balancing open accessibility with the tailored optimizations that made the Steam Deck a hit. Further software tweaks will bring ecosystem stability and improved performance, and we expect Valve's partners to join and develop better integration with SteamOS, too.
