Valve Updates Steam Linux Client To 64-Bit Architecture
The latest Steam beta replaces the 32-bit Linux client with a 64-bit version to improve performance, memory access, and library compatibility.
Valve moved the Steam Linux client to a 64-bit architecture in the latest beta update, replacing the previous 32-bit build.
You get better performance and stability in modern Linux environments because the 64-bit client accesses more memory, which addresses technical limitations of 32-bit address spaces.
Switch.
If you opt into the beta branch, you run the application as a 64-bit process. The transition matches the software industry trend of deprecating 32-bit-only application support in favor of 64-bit binaries. Consequently, developers working on Linux applications can expect the client environment to maintain better compatibility with modern libraries and system architectures.
