I still use VMware Fusion 11.5.3 on High Sierra 10.13.6 ("such outdated VM software" on an outdated OS). But it is exactly the point because it uses VMware's hypervisor instead of Apple's.
Apple's hypervisor has serious performance problems when it comes to nested virtualization (especially on Intel CPUs that lack a hardware feature called VMCS Shadowing). It STILL has not been resolved satisfactorily as far as I know. And I do not expect Apple to do anything about it now that its focus is on Apple Silicon.
VMware actually sort of admits this problem here :
When it says :
Starting with Fusion 12.1.0 VMCS shadowing is no longer required to use nested virtualization on macOS 11.0 however performance of nested virtualization without VMCS shadowing may be degraded.
"May be degraded" is a kind way of saying it. It is actually so slow as to be unusable. Even for those CPUs that support VMCS Shadowing (which exclude many of the CPUs Apple used in iMacs and Macbook Pros) there is still a substantial performance hit as far as I can ascertain.
As an example, it seems that my own i7 9700KF does NOT support VMCS Shadowing (in the Intel specifications it lacks "Intel vPro Eligibility", which if present apparently is Intel's way of saying it supports VMCS Shadowing). Curiously, the i7 9700K does support it. This means that if I were to run VMware Fusion 12 / 13 on Monterey / Ventura I would have run into these problems.
It is why I won't upgrade VMware Fusion any further. I will continue to use VMware Fusion 11.5.3 (and the corresponding VMware Workstation 15.5.2 on my Windows PCs) regardless of any "large security threat" (that I consider is blown way out of proportion anyway).
