Eventually, yes you are correct, but if it's bad on a VM, it's almost certainly going to be bad on bare metal. If it's good on a VM, thats an encouraging start and then the next step would be a bare metal test. But not everyone has a spare PC laying around or the know how/desire to start partitioning things.
Sunspark VM just uses the VM's driver which in turn is running inside another driver, perhaps on W7
If I run Windows 10 in a VM on my known good Win7 host, I get migraines. A host being good does not neccesarily mean the guest will be artificially good either.
And not for nothing, but if someone found that a Win7 host running a Windows 11 VM worked for them, they could just do that forever. If I ever get to the point where my hardware dies and I can't get Windows 7 to run on the hardware of the day, my plan is to install Linux on my PC, install VirtualBox, and run a Virtual Win 7 instance as my primary PC.
Runing Win11 in a VM also bypasses the TPM/SecureBoot nonsense and makes it an option for anyone who doesn't have supported hardware and isn't comfortable doing a wim swap or DISM install
