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

    i mean better efficiency is one thing, but having “so much better power efficiency” isn’t that large, especially under load. Arms major advantage is efficiency while doing lighter workloads, which is kinda the antithesis of a gaming device would be.

    What arm based designs excel at is if whatever workload utilizes some of the specific built hardware in them, which is why the modems and camera image processor on the snapdragon cpus are better than x86, because x86 designs dont really have dedicated hardware for those functions integrated fully(intel cpus do to some extent)

      That’s important too for gaming devices. It’s great the the steam deck can get 6-8 hours on low power games like Stardew Valley. A significant problem with many of the windows competitors is that they don’t see significantly better battery life at low loads. The original ROG Ally gets about 1.5 hours in a game like Cyberpunk 2077, but only gets 2-2.5 hours in a game like Stardew Valley.
