Yes. Valve has done a ton of work here because it's required to be able to run x86 games on a Steam Frame which has an ARM cpu.

Steam deck runs a full x86-64 AMD APU. The work valve has done for that was to get Windows games to run seamlessly on Linux.

Hopefully in 2026 the Valve Index VR headset which is ARM (Qualcomm?) we get what you're talking about here - basically proton for Win32/64 to Linux ARM64.

Side note that Windows on ARM isn't bad just that its priced out of its league and cooling is awful for gaming on current laptops. The only issue I had was OpenGL needing some obscure GL on DirectX thing for Maya3D to get games to work.

		To keep the chain of Cunningham's Law going, Valve's 2026 headset is called the Steam Frame, not the Index (which came out in 2019). But Valve's ARM efforts even mean that Android devices can play some (mostly less graphically intensive) Steam games. That makes me very excited about the prospects for the future of gaming handhelds.

As sibling pointed out, the Steamdeck basically runs a Ryzen 3 7335U which is x86.

The Steam Deck is pure x86, it's not an ARM-based CPU. The Steam Frame might be what you're thinking of.

		You're right. I was thinking of what I was reading about the Steam Frame
