This would presumably let x86 windows games run on ARM hardware.

This is almost certainly meant for the next Valve VR headset, but ARM has so much better power efficiency than x86 that a future ARM based Deck would be a huge improvement to battery life.

Also see this tweet:

VR games that have already secretly pushed Android ARM builds onto the Steam Store are ran via Waydroid (androidARM to LinuxARM)

VR games that do not have an ARM build on Steam (windows x86) are being translated/emulated via ProtonARM and FEX

Also, does ARM still have better battery life when all of the machine code has to be translated from x86? That adds a not insubstantial amount of CPU overhead, which does hurt battery life.

No idea, and that’s a pretty good question. The again some games run better on proton through Linux than they do on windows, so the performance overhead isn’t that bad.

True, but I feel like having to reroute x86 calls to ARM will produce more overhead than just Proton.
