Hello ! I am a beginner with unraid and I have a problem. When I created a gaming VM following the SpaceInvader One tutorial, I manage to launch it but when I launch at one the performances are very bad. For example on CSGO I find myself going from 250-300 FPS to 30 FPS, same on GTA I am at 15-20FPS against 60 in bare metal.

I also noticed that my GPU was used much less with the opposite VM than with a bare metal configuration (I tested with two GPUs), for exemple on GTA my GPU is used at 99% while with the VM it is only at 15-30%

 

Config :

2697 V2 x2

X9DRI-LN4F+

768GB DDR3 ECC

M6000 24GB

T600 4G

Samsung 860 Evo 250GB

 

Thank you in advance for your help !

I am experiencing the same thing. Interested to see what we learn. I have been using unRAID for 7 years and passing through my Nvidia card. Just got a 6700xt and a 165hz monitor I can't get over 70 fps in infinite. But bare metal I get 165 fps.

Which tutorial did you follow ?

Spaceinvader. I am passing a vbios I dumped from the card and an nvme stubbed through.

The only thing I was going to revisit was doing the xml as a multifunction device for the graphics card.

Have you watched the spaceinvader video for that edit? I was going to try that and the msifix

I did exactly the same thing but without result, I also tested the three bios, and several versions of Q35 & I440fx, I tested with windows 10 & 11 but I still have the same problem and I do not understand where it can come from ;-;

You did the pass through as multifunction device?

The only other thing I was reading about is special hyperV options.

I also isolated my CPU cores and pinned them to the VM so only the VM can use them.

Yes I did and I disabled the hyper-v

Interesting. I have been running hyper v on. I guess maybe someone else will come chime in. They will probably want your xml posted in a code block on this post.

I realize we can't have 0 losses but what you and I are seeing seems wrong for this much frame limiting.

Which OS vers are you running.

Is the PCI slot and the allocated CPU cores on the same NUMA node?

Not sure if you will need to enable Hugepages to get the throughput.

Hello !

Windows 10 22H2

And I put the M6000 on the first X16 slot so in principle it is the second NUMA Node

I have not tried hugepages, but there is a thread here

I just activated Hugepages and I still have bad performance with the GPU which is almost not used

Does the card have HDMI so audio and video pci devices in iommu? I don't see multifunction but notice you have an m6000 which may not split?

They each have their own group

Still everyone seems to preach combining them using multifunction to appease the drivers

I don't have an integrated sound card ^^'

It's the audio portion of the Nvidia graphics card you are supposed to combine with the video portion into a multifunction device. unRAID by default splits it into two pci devices which is physically impossible. I am unsure if it actually fixes performance doing XML edits but it's one thing I haven't tried in my quest to fix the low graphics usage.

The one thing I find as a clue is amd overlay won't work on VM but does in bare metal. This leads me to think something in the driver is bottlenecking. I was going to swap my 1070ti back in and test it bare metal vs VM but then my SAS card died last night.

I have no idea but, you should set gpu as multifunction, as said:

    <hostdev mode='subsystem' type='pci' managed='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x83' slot='0x00' function='0x0'/>
      </source>
      <alias name='hostdev0'/>
      <rom file='/mnt/disk1/isos/vbios/m6000vbios.rom'/>
      <address type='pci' domain='0x0000' bus='0x04' slot='0x00' function='0x0' multifunction='on'/>
    </hostdev>
    <hostdev mode='subsystem' type='pci' managed='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x83' slot='0x00' function='0x1'/>
      </source>

      <address type='pci' domain='0x0000' bus='0x04' slot='0x00' function='0x1'/>
    </hostdev>
    

 

Check bios settings, maybe you have some bios options that throttles pcie devices, like it happened here:

https://forums.unraid.net/topic/129030-gpu-throttling-while-in-game-low-fps-low-gpu-usage/?do=findComment&comment=1175669

 

This is particularly true for hp servers, but I don't exclude that it happens with other builds.

 

Check irq sharing issues with msi utility, there are relevant posts and the utility in this forum.

 

@hot22shot suggests a change to the xml for large memory gpus, to expand the mmio address space to 64Gb, by adding this at the bottom of the xml before the domain closing tag:

  <qemu:commandline>
    <qemu:arg value='-fw_cfg'/>
    <qemu:arg value='opt/ovmf/X-PciMmio64Mb,string=65536'/>
  </qemu:commandline>
</domain>

Edited November 30, 20223 yr by ghost82

In my case the VM did not boot at all : black screen and a core at 100% for a few seconds.

So I'm not sure it is the root cause, but anyway applying those settings won't do any harm.

Hi ! Thank you for helping me !

 

I tried editing the XML file but it didn't work, now I'm looking for an option that matches HP's but I don't think Supermicro has one on their older motherboards ^^' I continue my research !

I am having the same issue of not having full GPU usage. Everything else works fine as intended. On my rtx 3080. Cyberpunk 2077 stuck at below 58 fps and seeing lows into the 15 fps range. When I get 90fps+ constant on bare metal. 

 

I will attempt the hugepages fix, once I make it home, but I have tried....

 

1. Uninstalling/ reinstalling the drivers using ddu.

2. Trying to remove the -hyperv code from my XML windows config file. But this line does not exist in my XML config.

3. Disabling windows virtualization within windows,  but that option was already unchecked.

 

There has to be some checklist out there of things to attempt to fix this, this seems to be a very common issue.

Yep all of us gamers seem to be losing frames bad lately. I am on Ryzen and AMD and still same issues. I did notice this morning in halo infinite bare metal I am average of about 20 percent CPU but in the VM I was 70 to 80 percent on same settings. I am using CPU passthrough but it seems like it's bottlenecking
