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.
This is something I’ve always wanted from them ever since I learned that the current ways that emulate x86 use proton on top of a bunch of other stuff. Would love if this was able to be used on phones.
