Windows runs faster on a VM under linux than on bare metal
Can you detail your VM setup? I’ve tried Windows 10 on several occasions using Qemu and VirtualBox and the UI lag has been complete ass, even after installing the driver packages for each VM host.
To have any chance of doing serious CAD work in a VM you are going to need to set up GPU passthrough so the guest OS can access the GPU directly. AFAIK Virtualbox doesn't do this. Some hints about further research can be found at https://en.wikipedia.org/wiki/GPU_virtualization.
I strongly doubt Windows will be faster in a VM, that's a pretty bold claim. But it should be possible to get it to an ok level.
How can that be? It's the same machine except you have introduced some overhead.
it's a half truth. a compatibility layer will always be slower than bare metal but main systems tend to get bogged down with excess software and general use. A VM will be optimized for the 1 thing you need to run, and maybe even use a snapshot so it's always the same system at max performance.
