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

    IIRC, the M chips also have a couple of specific hardware accelerators for some parts of x86 code that ARM devices would usually struggle with. That’s something that other ARM chips (presumably) don’t have.
