I am giving up on VM Gaming

If I am remembering my build from the time, I had an RX 580 for Linux, and a GTX 1070 as passthrough to the Windows VM. At first, it felt like I was "giving up" on solving some problem that felt like it should be solvable, but it worked so well that I couldn't argue with the results.

It also assumes you have a motherboard with the right slots and enough PCIe lanes to get the performance out of two GPUs, and assumes you have a PSU with the power budget to support both GPUs. It definitely was a compromise, not perfection.

*Approx 2017 to 2020, before Proton or when it was was still new/immature. I now no longer care enough about games to play one when it doesn't just work on Linux. I assume the author does not feel this way.

I run CachyOS on my gaming PC now and I'm pretty happy with it.

This should work without needing a reboot. You do have to bind the vfio driver at boot, but the archwiki gives a script to unbind vfio and load the Nvidia driver: https://wiki.archlinux.org/title/PCI_passthrough_via_OVMF#Bi...

Which anecdotally worked fine on my RTX3050.

I did give up as well though, all of this is just too much of a faff. Hopefully Intel continues to make strides with their discrete graphics. They are the only manufacturer without DRM blocking this feature which the hardware can obviously do.

Giving up because you can't solve 'cold fusion' is a common mistake, when we so focused on the problem and forget the goals

At some point is just cheaper to get a second cheaper GPU. Or use a CPU with integrated GPU

> GPU has to be bound to VFIO at boot

You can bind and unbind them at any time. There are several guides for people doing it with only 1 GPU

Just keep it simple

With an amd gpu, using virt-manager I can GPU/USB passthrough with just a few clicks and no command line needed

I also like gentoo QEMU guides https://wiki.gentoo.org/wiki/GPU_passthrough_with_virt-manag...

The other day upgrading VM Win 10 nvidia drivers got a black screen, and was able to copy it as many times to install again other versions

I get throwing in the towel with all these issues but I personally didn't encounter half of them.

- I bought windows 11 retail on a USB stick. (before the AI nonsense, etc)

- I run windows in a VM without a network interface. This eliminates SO MANY PROBLEMS. microsoft being problem #1

- I disabled all nonsense, windows defender was slightly harder

- I share a drive with linux (only one booted at once)

- linux runs lgogodownloader to load all my gog games onto the shared drive

- I install the games under windows from the shared drive

- someday I might change shared drive to virtiofs

- gpu passthrough

- I pass through an entire USB controller for audio, and plug in a USB schiit dac + headphones. passing the controller is key for glitchless audio

- some day maybe I'll figure out a steam VM. like maybe connect stuff once, download game for offline play, then take it off the network forever. Maybe have VMs for collections of games.

Yeah, we really live in age of Internet Explorer 6 yet.

We already have cool features in browsers, like transparent backgrounds, rounded borders, and even HTML 5 video elements, but we still cannot use VM intensively for any purpose with no hassle.

Maybe 10-50 years later we finally can use Linux laptop with RTX 5060, and just run a Call Of Duty multiplayer while a local LLM will fix bugs in our code.

So for someone who is constrained to one PC, is dual booting the better option, or is there something else?

I am currently using unraid as my server and used it for gaming as well ( though deck mostly took over that particular distraction ). In a sense, playing in VM was the initial draw. I stayed for everything else.

But the points the author is making kinda contradict themselves. Before I go to the actual claims within the post, please be aware that gaming these days is not exactly cheap. Technically, neither is running decent NAS, or server or anything these days. Not really. However, if you are trying to trying to do VM gaming ( and gaming is generally resource intensive ) and run NAS and docker and whatever else tickles your fancy, you cannot reasonably complain, because, well, you set it all up..

Claims:

<< Today I wouldn't recommend it to anyone unless you are severely constrained in your budget or space.

Again, this whole thing is backwards. Unraid is not about budget or space. If anything, doing it well may end up being more expensive especially if you want to do gaming, AND docker, AND mebbe CV and random testing VMs and backups and NAS.

<< I am currently running 60 docker containers and idle at 14GB/32GB free RAM with a cpu usage of 10% across all 6 cores, starting the VM reserves my RAM usage to near max,

Does it sound more like an actual user issue? I might not be a heavy user, but there are very few times, I run things at all times. I can't tell if the user is complaining that unraid does not do schedule resources for them ( turn off things as it sees fit ) or expects that docker magically requires less resources.

<< Multiplayer games and anti-cheat

About the only semi-valid complaint, but here it is not even an unraid issue. It is gaming ecosystem issue, but I am willing to accept it, because there is really no solving without gamers as a group actually agreeing on maximum level of bs they are willing to accept.

<< KVM XML tuning became a constant maintenance task to avoid regressions, lag and lockups. I experienced VM degradation, Windows VMs that used to work properly became unbearably slow for no apparent reason

I suspect that the author had some sufficiently custom setup, because while none of my stuff is edge tech, I never ran into a problem that did not, at the end of the day, result from somewhere between the user and keyboard. You do have to learn a lot ( if you did not know anything about virtualization beforehand ), but that is true of most linux distributions in general. By comparison to where it used to be, the ecosystem now is fairly user friendly.

<< Another interesting use case would have been running multiple VMs using a single GPU. You can attach the GPU to multiple VMs but by default only one VM can be running which utilises the GPU.

Semi-reasonable issue, but the appropriate approach here is multi-gpu rig, which, again, if you buy into unraid for VM gaming, is, maybe expected is too strong, but, but complaining about it is like pouring cheap leaded gasoline to a lambo.

<< I was hoping I could use the GPU if the VM was not used for docker containers. This is possible but not user friendly, the GPU has to be bound to VFIO at boot.

Here I am willing to agree despite not running into that issue sine I use dedicated box for more intensive gpu stuff that is not gaming.

But it's mainly because I do not target anymore games with stringent anti-cheats or with high setup requirements (though the M5 is quite powerful right now), and a lot of games are ported natively to macOS but not Linux (most recent to date is Age of Empire 2 Definitive Edition 1 week ago).
