Adding more than 2 cores (and the HT pairs) to my Windows 10 VM causes major stuttering.

Using a Ryzen 2700x.

 

I've tried various groupings of cores (always along with the grouped HT pair) and anything over two cores causes the entire vm (mouse included) to massively stutter every couple of seconds.

 

I've tried everything under the sun and this is the only way I can get a stutter-free Windows 10 VM.

No where near an expert, or even knowledgeable but, from reading the threads here is there a major latency problem because of NUMA pairing? (or something like that).

 

Maybe google "unraid numa"

For some reason I thought Ryzen chips only had the one node or whatever.

Check out the spaceinvaderone videos on installing lstopo which will give you a visual representation of your numa nodes, the CPU's & PCIe slots tied to them. This will help you pick your CPU assignments.

Here's my lstopo output. Not exactly sure how to interpret it since it's a different type of CPU than spaceinvaderone's example.
