I've switched hosts so I would have to run a series of tests to compare.

There are a number of new variables:

1. Windows 10 release (I'm now on Windows 2004)
2. My host OS is now Manjaro
3. CPU is now AMD Ryzen 3900X (before it was Intel 3930k)
4. Kernel is 5.8.18-1-MANJARO
5. qemu 5.1.0
6. libvirt 6.5.0
7. New VM configuration using virt-manager/libvirt with EPYC-IBPB model instead of host-passthrough, instead of a qemu bash script to launch the VM.

Time permitting, I plan to replace Manjaro for a Ubuntu 20.04 based distro. But this will not happen in the very near future.

In the meantime I will do some a/b tests with spectre protection under Windows enabled/disabled to see if it is still an issue.
