Key information
Valve addressed user reports on GitHub by confirming that the Steam Client for Linux operating systems is not officially supported on Arm architecture. A developer explained that official support remains restricted to AMD and Intel x86-64 processors, maintaining a long-standing policy.
The developer noted that proper functionality on Arm hardware would require extensive optimizations. However, Valve believes the limited potential user base may not justify the required effort.
This limitation exists despite Valve optimizing SteamOS and porting Proton 11.0 to the Qualcomm Snapdragon 8 Gen 3 platform for the Steam Frame VR headset, enabling x86 games to run on Arm. Nevertheless, the Steam Client itself lacks official backing.
Modders are utilizing the ARM64 SteamOS port to transform Android handhelds by Ayaneo, Ayn, Retroid, and Konkr into Steam Deck alternatives using projects like Armada. Despite these community efforts, users should not anticipate official troubleshooting or fixes from Valve.
