Some folks have raised the possibility of a more affordable Arm-powered Steam Deck, but we don’t think that’s likely.

Proton is Valve's solution for running many Windows games seamlessly on the Linux-based SteamOS. The leaked code shows Valve testing this ARM64 version with a wide

Valve may be developing an ARM64 version of Proton for Linux gaming. Hundreds of games, like Left 4 Dead, have been tested for compatibility using a new 64-bit layer. The potential for ARM64-based portable consoles opens exciting new possibilities.

Valve are likely up to something hardware-related again, report NotebookCheck. Their next chunk of plastic and wires – following the Valve Index, Steam Deck and Steam Deck OLED – could swap PC gaming’s favoured x86 architecture for ARM, the type of processor favoured by the Nintendo Switch, Macs, and mobile phones.

Eagle-eyed users have spotted a test application on SteamDB suggesting that Valve is experimenting with Arm64 support for Proton, the software that enables Windows games to run on Linux systems.

In a move that has sent ripples through the gaming community, Valve has confirmed that it’s actively testing ARM64 support for several of its popular games. This development has sparked intense speculation about the company’s potential plans for future hardware,

Valve appear to have some pretty ambitious future plans for Steam, as we've seen recently a leak (and not for the first time) that Valve has plans for ARM64 and Android support on Linux.

Valve is bridging its x86 library with ARM framework support for possible Steam games on mobile. The focus on ARM64 hints at expanded cross-platform support for SteamOS. Speculation includes Steam games on mobile and the potential development of Valve's standalone VR headset.

Valve, which operates Steam, the largest online marketplace for PC games, has worked hard to hedge against the possibility of Microsoft turning Windows into a closed marketplace-Linux gaming is taking off and Valve branched out into hardware to run it.

The Steam Deck might be the most popular Linux PC ever, though you’d be forgiven if you haven’t realized that its SteamOS software is technically Linux. The Proton compatibility layer is the Steam Deck’s special sauce,

Proton, a compatibility layer developed by Valve and CodeWeavers, lets Windows games run on Linux-based systems like the Steam Deck. These tags suggest that Valve is working on an ARM64-optimized version of Proton,
