Is Microsoft working on a compatibility layer like Apple did? If no then 2024 is just another x86_64 year filled with bullshit news and hype train conductors.

There’s already a compatibility layer. Microsoft had one before Rosetta 2 was available. You can test it yourself with many windows on arm dev builds that exists, or with a Mac running windows in a VM.

Verdict; not as good as Apple (not sure how it compares with the one from Linux) but good enough. https://beebomal.pages.dev/posts/apple-s-rosetta-2-vs-windows-x86-emulation-explained/

It isn’t as good because Rosetta 2 exploits some custom features built into the their M processors. Specifically, there is a special mode that strengthens the memory model, which is critical for both performance and correctness when it comes to executing multithreaded x86 programs on ARM.
