Unfortunately this seems to target the Surface RTX Spark dev boxes Microsoft is planning to release later this year and no other GPU’s.

Wine will just use the GPU capabilities of the Mac by mapping DirectX/3D calls to Metal. No need to keep any Windows installation, ever.

Also here we are running Amd64 (64 bit Intel, but I use Amd64 for the original architecture) games into ARM with the translation layer. It might have a performance penalty but most WIndows games are Amd64/i386 CPUs anyway.

The video link I gave to you it's a guide to setup Windows' Steam release under MacOS+Wine. Once it's installed you just click on the launcher and that's it, Intel PC Steam under your Mac.
