Problems with VMs on a AMD-OSX hackintosh

Hi guys

I'm currently having black screens or consistent crashes with both VMware Fusion and Parallels 13 and 14. The main issue is when trying to boot to create a new VM with windows, the apps refuse to boot anything.

I'm currently on High Sierra using AMD-OSX's 10.13.3 kernel for Ryzen. I've tried Nvidias 106, 156 web driver versions and it's made no difference. I have CUDA installed, IOMMU support enabled and AMD's Virtualization extension turned on.

I have a Ryzen 1950x, GTX 1080, 2 NVME SSDs, 2 SSDs and 2 HDDs.

Anyone ever experience issues like this?

Also, given how poorly High Sierra performs, anyone recommend going back to something like Yosemite?

Thanks!
