Factorio Runs Natively on ARM64 Linux: Wube Explains Its Steam Frame Work

In Friday Facts 446, Wube Software describes porting Factorio to ARM64 Linux. Valve’s Steam Frame prompted the work. The studio uses its support for conventional two-dimensional games; the report does not announce a separate VR play style or a new factory interface.

The technical work began with cross-compilation from x86 to ARM64. Wube needed the appropriate target architecture, system files for that platform and a suitable linker. The developer report names Clang, Mold and eventually debootstrap as tools used for this setup.

Existing Linux Players Were Affected Too

For Steam distribution, Factorio moved to Steam Linux Runtime 4.0 because its previous version, 1.0, lacks ARM64 support. This runtime change is a global setting and affects other Linux players too. An updated Steamworks integration also introduced an important bug that required a hotfix.

Wube reports a first successful launch on the development device in February 2026 and later use during its internal LAN event. According to the report, no architecture desync occurred between ARM64 and x86 there. This is a specific development observation from the studio, rather than a network measurement reproduced by our editorial team.

The described device test used Steam Deck graphics settings and 720p. Its successful operation cannot be extrapolated to every factory size. Factorio’s simulation load grows with the facility; a reliable performance comparison requires identical saves and clearly documented conditions.

The port’s immediate benefit is an additional native architecture. The comfort of lengthy factory projects on Steam Frame remains a question for actual device testing. The report explains the implementation and results so far, without establishing a universal recommendation for every production world.
