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

Edit: here's gamingonlinux coverage of this info, includes some more information

does ARM still have better battery life when all of the machine code has to be translated from x86

afaik macos/rosetta is more efficient than native windows/x86, but that could be down to OS integration, or any number of confounding factors… i’d suggest though that x86 windows applications sometimes run better and more efficiently on alternative platforms, even with the translation layers - whether that’s down to the instruction set or a combination of factors
