GoKawiilValve makes Steam's Linux client 64-bit in latest beta update
Valve's newest Steam Client Beta update converts the main Linux client binary from 32-bit to 64-bit, matching components like steamwebhelper that were already 64-bit. Linux users will still need some 32-bit libraries and graphics drivers, as Valve says pure 64-bit-only Linux distros aren't yet supported. The update also introduces the Steam Runtime container for consistency across distros and a new Steam Achievement Sets feature already live in games like Left 4 Dead 2 and Portal 2.
GoKawiil's interpretation of the reporting above, not reported fact.
The shift could expand memory access and improve security and stability for Steam on Linux, reinforcing Valve's growing investment in the platform following the Steam Deck's success. Because full 64-bit support isn't ready yet, distro maintainers weighing whether to drop 32-bit library support—like Fedora did last year before reversing course—may face continued pressure to keep legacy compatibility in place.
- Steam's main Linux client binary is now 64-bit, not just supporting components.
- 32-bit libraries and drivers are still required since full 64-bit-only distros aren't supported.
- The beta also adds a Steam Runtime container and Steam Achievement Sets for cross-game progress tracking.
