Update

 

I switched to a 7950x, no problem anymore, my GPU is used at 100% with full perf

Same I upgraded to a 5950x last year on a good deal, no more performance problems, with 64gb of RAM

hi, i had similar issue (games working poorly in windows VM with passthrough GPU), I tried the recommendations in this thread and various other threads without help (i tried the timesource setup, disable hyperv in VM definition & inside the guest i disabled services, migration off, providing rom file to the gpu, etc) and i fixed it by adding the emulatorpin tag in the xml pointing to the core 0 and it's thread.

Somehow the template for windows 10 or windows 11 does not include this emulatorpin tag, the moment i added it manually in the xml it solved the issue. 

BTW, i'm having an older Xeon E5 v3. 

This just started happening to me in Monster Hunter Wilds after playing 70ish hours without any issue (RTX 3080). I took a break from playing and in the interim I updated my motherboard bios, changed a few settings, and swapped nvme drives (both installations were baremetal). Now once the game starts my GPU utilization drops to 20% and my fps goes down to 10-12 no matter what graphics settings i select. Oddly I get full utilization in on the title and character select screens.

I've tried all the suggestions in this thread but nothing has worked. I'm at my wits end here. I figure it must be an unraid setting or VM config that's causing the problem, because the game runs fine when I boot directly into windows. I've even tried creating new VMs with very basic settings, and installing on vdisks instead of baremetal and it's the same everywhere.

Of the games I'm playing I'm only having this issue with Monster Hunter Wilds. the other games are not very graphically intensive. Furmark benchmarking runs just fine as well.

What CPU are you running? I had to dedicate a min of 8 cores and 8 threads for my performance to improve on my Windows vm

i5 12400. I gave my VM access to all cores, and also tried giving all cores but 0/1 pair.

The VM I was running when it was working had all 12 cores btw.

Is this the 6 core 6 thread CPU?

If so, you may need a stronger CPU. When I initially created this thread I had a 3600x which was a 6 core 6 thread part. And cyberpunk was essentially running only on 4 cores and 4 threads. ( 2 was reserved for unraid) That's equivalent to like a 2012 cpu. It's just not strong enough for modern games.

I'm now on a 16 core 32 thread CPU. And games run fantastic because I can dedicate a full 12 cores and threads now.

Your GPU is being bottlenecked by the CPU

I think you missed the part where I put 70+ hours into the game in a similar (but not the same) VM. something changed in the last couple of weeks to cause this, and I cant figure out what it was.

did some more digging around, THIS solved it. Still have no clue what caused this to begin with.
