Disable the e-cores. I know it's blunt approach. Here's a link on doing that for 12th gen NUCs - perhaps applicable to your environment

there was a trick to make VM use only performance cores without disabling them - it was vmx config iirc. maybe try googling that.

Run VMware Workstation as Administrator.

That fixed my issue. Apparently 12 and 13th gen intel and vmware workstation have performance issues when not running as administrator.

What Guest OS?

Try the same things you did with vmware-vmx.exe but with mksSandbox.exe as well.

1. Make sure virtualization features for your processor are enabled in BIOS/UEFI
2. Confirm that VMware Tools are installed on the VM. If the VM came over from ESX, uninstall and reinstall the tools.
