Most of these will run in a VM just fine. I have a barebones 'just installed' win10 image that I use to clone a new VM for each new app I add. Solidworks, NX, Cadence, Altium and ISE all work fine with no problems because of 3d acceleration or such. Admitably my impetus for this was conflicting FlexLM emulators cough, but there's no reason it can't work just as a way of keeping things organised and clean on a host OS that isn't windows.

> Most of these will run in a VM just fine. Emphatically, no. Running CAM, or CAD software, in a VM, is almost unusably slow with any large models. I’ve tried. It’s not fun to zoom through a large model at 5 FPS. You need to have GPU passthrough, and even though you can make that work, it’s very risky (hardly a stable sane thing to build a business on), and you’re just running Windows again, but worse. We need GPUs in Windows already (primarily NVIDIA) just to keep the CAD from being too slow, and to keep our rendering options open. Even if it worked brilliantly in a VM (which it doesn’t), why would I double my operating systems and run them simultaneously? That’s just begging for compatibility issues, frustration, and defeats the point of avoiding Windows entirely. Any benefits for avoiding Windows are almost completely negated.

  CAD is exactly what I'm using VMs with GPU passthrough for, and it's working briliantly there. The advantage is that most of these VMs have no internet access at all (they only see a single SMB share on the host) - so most of the security and privacy issues are just non-existent.

You can with a tremendous amount of effort create a brittle config that will run some of that software acceptably, especially if you're sailing the high seas. In a real world situation it's an absolute no-go.

Running Windows in a VM us still running Windows. I would consider Wine instead, or Proton. It may work really well with some software, but may have trouble with other software.

  Wine won't work with a lot of the enterprisy stuff that also requires license servers, etc. Besides the design stuff, the entire manufacturing industry is dependent on Microsoft. There are thousands -- probably hundreds of thousands -- of air-gapped NT4 machines in factories running very specific but unsupported for 20 years software, for example. All the big MES systems, test software, and various tooling to run factories are all designed for Windows only.

    This is correct. Some of that software, especially for controlling specific hardware, can even be DOS software. The hardware can be reliable and expensive; software support, long unavailable.

  Wish it worked with SolidWorks. Their compatibility page for that application is mostly "Garbage" rankings.
