The translation feature that minces x86 to ARM is done. x64 is still in the works.

Curious if you have a source on the x64 part I can read up more about?

Mainly wondering if I buy an ARM Windows device today, is it just a matter of upgrading Windows somewhere down the line for x64 support? Or will I have to shell out for brand new hardware?

It's not clear what the status is. But I doubt that new hardware is required if it releases.

How is the performance?

Certainly performance wise - better than expected, but gets down to what DX level the game is using, Rpi's not known for much graphics grunt. Though these two examples running well on the rpi4 with windows 10, better than you'd expect and kinda impressive.

And that is all running in software mode. The RPI4 has no working GPU.

I don't know much about it, so this has me curious. The specs say the BCM2711 has an integrated Videocore VI GPU. Are there just not drivers, or what about it makes it "not working"?

Broadcom didn't release GPU documentation yet, with only Mesa being available for now.

+ developing Windows GPU drivers isn't trivial

So it works fine with Linux then, yes? :-P

Yes, on Linux it’s good: https://github.com/const-me/Vrmac/

Even h264 video acceleration is there: https://github.com/Const-me/Vrmac/tree/master/VrmacVideo

Too bad h265 hardware decoder doesn’t yet have a V4L2 driver.

Very slow. Someone I saw on YouTube tested a couple simple platformer. X86 games on the Pi 4 and got 2-4 FPS.

But it's neat that it works... there are plenty of simpler enterprise apps that would run just fine without a ton of performance.
