After changing CPU and upgrading Unraid Windows 11 performance is really poor

[Cliff]

I had alot of problems where my server was constantly rebooting for months and the troubleshhoting driving me crazy I finally found the problem that was the CPU (after replacing both PSU and motherboard).

I replaced my Ryzen 3900x with a Ryzen 5600G until I get a new one back from the RMA process. The Ryzen 3900x had 12 cores and the 5600G has only 6 cores but I have assigned the same amount of cores to my Windows 11 VM (4 cores). I also upgraded to Unraid 6.10 after changing the CPU, but I notice that my performance is really bad. I am passing through a raw nvme disk to my windows VM and also a 1060 GPU with bios but even when I play really old games like Grim Dawn it stutters/lagging like crazy. 

I tried running Cinebench anf I got a score of 5400 points with four cores instead of six but when looking in the database a stock 5600G should get around 11200 points so from my calculations I should get around 7400 points if it was scaling properly. The only thing I can remember configuring differently this time was that I used OVMF TPM bios and selecting Q35-6.1 instead of 5.1, everythin gelse is the same (raw nvme ssd disk, 16GB RAM and passing the GPU with bios)

Does anyone know what can cause the performance degration ? When using the 3900x I could not notice any differnence at all from when I just booted Windows 11 directly from the nvme.

Check latencies with latency monitor (search google for this), for example, and eventually fix shared irq by switching from line based interrupts to msi, with msi utility.

You will find info and msi utility in this forum.
