[Performance problem with a gaming VM]

Update

 

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

@DarkyCage like ryanm91 wrote, I would try with 12-23 and 36-47 to see if there's any difference.

 

@Mrtj18 I think that your CPUs should be powerful enough, I mean yes the 3600x is not new but 6c/12t is still relevant IMHO.

 

Did you tried to look at what your VM CPU was doing during a benchmark, using a tool like perfmon ?

This could tell you where the bottleneck is if any. IO for example would be a good culprit.

I still have poor performance ;-;

Sooo have any of us tried disabling virtiofs which is new default in unRAID template?

Nop what is that ?

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 !

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

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

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?

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

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

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

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

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 ;-;

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 ?

[Performance problem with a gaming VM]

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 !

Je pense qu'il y a des différences de performances suivant le type de 'Machine' que tu utilises, mais là je ne sais pas dire si le Q35 7.1 est un bon choix ou pas. 🤷🏼‍♂️

 

Peut-être que quelqu'un d'autre sur la section francophone aurait des suggestions.

 

Sinon, il y a la section anglophone, la partie sur le VM en particulier :

[Problème de performance avec une VM gaming]

Bonjour merci !

 

Oui j'ai isolé des cœurs dédiés pour ma VM

J'ai essayé sur SSD Sata & NVMe et j'ai toujours le même résultat

[Problème de performance avec une VM gaming]

Bonsoir !

 

Je suis débutant avec unraid ! Et il s'avère que j'ai un petit problème avec les VM sous windows, elles se lancent et fonctionnent mais niveau performances je passe de 270 FPS sur CSGO en bare metal à 30 sur la VM et j'ai le même problème sur tous les jeux. J'ai essayé pas mal de choses mais je n'ai pas trouvé la solution ;-;

 

Je vous remercie d'avance pour vos réponses !
