Valve says its standard Steam for Linux client is not currently supported on ARM-based hardware. On October 4, 2026, the Valve-associated kisak-valve account used that wording in a reply to a Remote Play issue and pointed to a feature request opened in 2015. The statement concerns the Linux client’s platform support; it does not mean Valve has no ARM gaming work underway.
What Valve said about Steam on ARM
In a reply posted October 4, 2026, to Steam for Linux issue #13689, the kisak-valve account wrote: “Steam for Linux is not currently supported on ARM based hardware (#4061).” The reply closed that report as a duplicate and directed readers to issue #4061. Read the Steam for Linux issue #13689.

The wording is a statement about support, not a declaration that Steam can never run on ARM or a published roadmap for future compatibility. The referenced issue, “can’t run on ARM architecture systems,” was opened on October 12, 2015, and remained open when checked. It is labeled a feature request and reviewed; its original report describes an installation failure involving missing 32-bit packages. Its age and open status do not explain Valve’s support boundary or promise a future change.

Issue #13689 concerned one user’s ARM64 Remote Play setup, not a general compatibility survey. The reporter said Steam’s ARM64 beta client used V4L2 hardware decoding but did not offer AV1, although the device’s decoder listed AV1. The report includes a diagnostic trace and says decoder enumeration stopped after H.264 or HEVC. These are the reporter’s observations, not independently verified findings about all ARM devices or Steam clients.

The report identifies an AYN Odin 3 handheld with a Qualcomm SM8750 chip, Fedora 44-based Armada distribution, kernel 7.2.6, and Steam client build 1790904859. That describes a third-party device and software configuration; it does not establish official support for that handheld, ARM Linux generally, or every ARM64 Remote Play configuration.
What Valve documents for its standard Linux client
Valve’s Steam for Linux README lists the latest Ubuntu or an Ubuntu LTS release and a 64-bit x86_64/AMD64 Linux kernel. It also lists x86_64/AMD64 and i386/IA32 libraries. Those are the published requirements for the standard Linux client described in the README, rather than evidence of general desktop ARM support. See Valve’s Steam for Linux README for the current requirements.

“Steam on ARM” can refer to different layers: installing the Steam client, running games through Proton, streaming gameplay from another computer, or using a device’s video decoder. Support or development at one layer does not automatically establish support at the others. Valve’s Steam Runtime documentation describes Linux runtime and Proton container components, but does not establish general ARM desktop client support.

No. Valve’s GDC 2026 hardware presentation describes “Expanding Proton for Arm64 architecture” and says this “Allows x86 games to run on Steam Frame’s ARM chip.” That is evidence of ARM64 Proton development for Steam Frame, not a public commitment to support the ordinary Steam for Linux desktop client on arbitrary ARM computers. The distinction is between work to run x86 games through Proton on a particular ARM device and support for installing and using the standard Linux client across ARM PCs.

What to use if you want portable Steam gaming
For a handheld option on a platform Valve documents, Steam Deck is a relevant alternative: Valve describes it as a SteamOS device, and SteamOS uses Proton to run many Windows games. Steam Deck is not an ARM device, so it is not an ARM workaround; it is a separate, x86_64-based SteamOS platform. Valve’s Steam Deck page provides the device information.
