Is Wine similar to CrossOver? That seems a bit popular at least for Mac gamers.
But that's the thing, it doesn't need to run well. It can be dog slow, it can have crappy performance and resolution, it can require extra layers etc. I just need to be able to run them..
Just so don't misunderstand it. So I can have Parallels on my M1/M2, but only to install ARM Windows? Is it possible to install x86 apps in ARM Windows? I looked at
one app that I need and it says "Processor: 64-bit, x86 processor required (ARM processors are not supported)".
On an Apple Mx-based machine, you cannot run a virtualized x86/64 OS, so you've got to install Windows 11 for ARM via Parallels through the Windows Insider Program (free to join). There is
no retail version of Windows for ARM -- Microsoft has an exclusive deal with Qualcomm, so it's very unlikely that Microsoft will ever release a non-OEM/non-developer version of WinARM to the public.
The developer "preview" of Windows for ARM is unregistered. Some people have had success registering it with a retail code, but some have not. If you need Windows to be registered for whatever reason, YMMV.
Windows for ARM has a built-in x86 emulator (basically similar to Apple's Rosetta 2 for running macOS Intel apps on an Mx processor -- though has some technical differences). Not every Windows app will work; most will but some with direct hardware processor calls may not. You'll simply have to test your apps to see if they work or not. The only apps on Windows that I personally need (Office 365, Chrome, DrawBoard and a few others) work just fine. Since you noted that your app plainly states it won't work with ARM processors, I'm guessing they know what they're talking about since there are Windows machines with ARM processors, but there's only one way to find out.
The decision to support Windows on Apple Silicon rests completely with Microsoft. As of now, they don't appear interested, but they haven't yet actively tried to prevent it.
Performance of Windows for ARM via Parallels is fair. Works fine for Office-style apps, web browsers, etc.. Don't plan on editing any 4K video or running a high-performance AutoCAD session on it. And games are pretty much out of the question.
* The other option for "running" Windows apps on an Mx Mac would be to stick a cheap headless PC in a closet and run a remote desktop session to it on your Mac. Should perform quite well over ethernet or a good wifi network. While a little more work, it might be more elegant than having a second computer on your desk.
