Overview
- Valve released Proton 11.0-Beta1 with an official ARM64 build on its GitHub, adding FEX-2604 to translate x86 Windows games for Arm Linux devices.
- Community testers have already run the Steam client on Arm hardware, including a Nintendo Switch demo using Ubuntu that showed the Steam UI working.
- Early users describe the ARM64 path as unstable and slower, reflecting the cost of x86-to-Arm translation through FEX compared with native x86 execution.
- Beyond Arm support, Proton 11 rebases on Wine 11 and updates core components like dxvk and vkd3d, while fixing issues such as broken Steam Overlay in many EA games and restoring VR features in titles like No Man’s Sky.
- The beta also expands game compatibility, making classics like Resident Evil (1996), Resident Evil 2 (1998), SHOGUN: Total War, Breath of Fire IV, and Deadly Premonition playable, which hints at a broader push to grow Linux and Arm gaming before any full consumer rollout.
