CPU cores And Threads - macOS-Simple-KVM

I am trying to run https://github.com/foxlet/macOS-Simple-KVM

I have Mojave, 1080p resolution and 24G RAM working fine.

ISSUES

1.) I can not go beyond 4 core 4 thread in the settings or macOS just does not start up at all from clover just loads in a lots of lines than goes back to clover boot menu. I have a Ryzen with 8 core and 16 thread.

2.) Mouse tracking in incredibly slow and safari tabs has some strange black artifacts (I haven't made any since with the GPU that is an Nvidia 1080Ti, so that is why it is not a full fledged Hackintosh)

Thank you for your time, I appreciate that.
