Valve Tests Proton for ARM64 Compatibility, Hinting at Future Hardware Adaptations

Valve's experimentation with ARM64 support in Proton could pave the way for ARM-based devices, but a new Steam Deck is not imminent.

SteamDB entries reveal Valve is testing ARM64 support for Proton, which enables Windows games to run on Linux systems.
Popular games like Left 4 Dead 2, Garry's Mod, and Kerbal Space Program are included in the test application.
Speculation suggests this could lead to ARM64 compatibility for devices such as Android smartphones, tablets, or even future Steam hardware.
The ARM architecture has gained traction with recent Qualcomm Snapdragon X CPUs, enhancing Windows-based game emulation.
Despite the buzz, a next-gen ARM-based Steam Deck is unlikely in the near future, with power efficiency and compatibility being key considerations.
