Steam Linux client switches to 64-bit in beta

The Valve Steam client for Linux runs as a 64-bit application following an update released on October 15, pcwplus.hu reported. The change arrived via the Steam Client Beta branch, meaning only users opted into testing receive the new architecture so far.

Steam Runtime Container Integration

The updated client now operates inside a Steam Runtime container. Valve uses this exact technology for Linux games to reduce client dependencies on varying system libraries across different Linux distributions and to ensure consistent performance across diverse software environments, according to pcwplus.hu.

Ongoing 32-Bit Library Requirements

Transitioning the main application to 64-bit does not eliminate all 32-bit components. Valve maintains system requirements that mandate both 32-bit and 64-bit system libraries along with appropriate graphics drivers to preserve compatibility with older games, pcwplus.hu reported. Fully 64-bit Linux systems lacking 32-bit support libraries do not receive official support from the platform.

Valve Prepares SteamOS for Broader Hardware Distribution and Updates Achievements

The architecture shift coincides with growing Linux player counts driven by the Steam Deck and the Proton compatibility layer, pcwplus.hu reported. Valve has prepared for broader SteamOS distribution by adapting the platform’s compatibility framework for upcoming hardware like the Steam Machine. The same beta update introduces Steam Achievement Sets, letting developers organize achievements into distinct groups for base games, downloadable content, or seasonal releases. Valve has not announced when the 64-bit Linux client will graduate from the beta branch to the stable version of Steam.
