VM Performance compared to Unraid

I am wondering if anyone can help me debug, I have both UNRAID and prox running.

Server has 2x e5-2699v4; 768gb ram. (hp g9 dl380)

Unraid has ryzen 5 3600, 64gb ram

I replicated the same setup I had on unraid as close as I could, but even after a lot of changes and iterations with my prox settings, unraid is blowing it out of the water (at least GUI based VMs? ) using RDP

I am wondering if anyone has had similar experiences or wonder what the issue could be. I feel like with prox being type 1 hypervisor, the results should be opposite?

Would love feedback, and really hoping for some lol

Top video is prox, bottom is unraid.

**Also want to add that the performance difference is not just RDP connection. Another issue is compiling the same c++ program, almost instant on the unraid VM, whereas the prox vm noticeably hangs for ~5 seconds.

In both VMs I have tried various configurations with little/no success. The most successful was VM2, but still noticeably behind the Unraid VM.

Maybe it is video drivers? At least, that is the only thing I can see that are different in options

Might be relevant, but some cores seem to be running slower than others, unless I am interpreting wrong.
