Running Windows games on Linux in a VM using the GPU?

[Guest]

Hi

 

I want to switch to Linux completely, but I have some games that I want to play(Train SIm World, GTA V) that I can't get to work in wine.(Program to run windows apps on Linux natively)

I also have some other things I'd like to be able to test on a windows VM. So my question is, is it possible to have a VM use a GPU using pass through, but have the OS(Ubuntu) also use it.

I know it can be done with an extra GPU, which I luckily do have(RX480), but I prefer to use my Titan Xp(which then would be shared with Ubuntu).

The reason I don't just use my RX480 is because It isn't as fast, and it requires a pcie power connector(which I only have 2 of, which are connected to my Titan Xp). I'll try to run my Titan Xp with one PCIe power connector now though, but I guess that won't work.

 

So in short: How can I passthrough my GPU to a windows vm, and allow Ubuntu to use it too?(So no DirectX emulation layer and stuff, as that's slow)

(If that's actually possible)

 

Thx!

What CPU do you have? Does your CPU have an iGPU? Enable that in the bios as primary display source for Linux then pass through the TitanXP through to the VM.

 

Have you tried the new Steam compatibility tool for Linux; Proton? It's largely based off of WINE and is still in early days so you may not see improved compatibility over WINE, but might be worth trying.

 

Alternatively could you just dual boot in to Windows, or do you need the Linux OS running at the same time?

What PSU do you have?

Stop using Linux and go back to Windows if you want to actually be able to play video games

I only play video games like once a week for one hour. I want to use Linux because of multiple reasons:

1. I can finally have my privacy back. Since the Windows installer has literally an option to enable a keylogger.(which ofc is enabled by default and hidden)

2. I am more familliar with it, even though I kinda like the Windows 10 GUI.

3. Less wasted resources and forced updates. Plus all the standard crap ware like Minecraft and Candy Crush will be gone too.(which it reinstalls after deletion lol)

 

I tried running a GPU with one power cord:

That doesn't work. I'm surprised it did anything at all actually.

Sadly, no - you need a separate card for passthrough. You can use your lower end card for ubuntu and play all games on the VM though.

 

-edit-

for the power cord, you can use adapters from the sata connectors.

There's no reason to when he can use kvm...

You can't share a consumer grade between a vm and a host. Grid, tesla and some radeon pro cards allow this. But the easy option is to get a second gpu.

Ok, guess I'll have to buy a sata to pcie power connector then. I can't use my lower end card for ubuntu as I do 3D gmae engine programming, and I quite need the power. But I think the games should run pretty well on a RX480.

Wait.... SO it can be done actually? Didn't expect that to be honest.

Isn't there some driver hack maybe to allow it?

Ryzen R7 1700, it doesn't have an IGPU. I don't use steam actually, I don't like it. I need Linux to run at the same time.

I have a seasonic 620W 12something. I am sure it only has 2 power connectors.

why not just dual boot here?

no easy driver hack.

I NEED Linux to run at the same time, for now I'll do the dual booting thing. But I don't want to reboot every time I want to play a game for 10 minutes before I get bored. Also, I use the Windows VM for testing applications, for which I need to also have Linux running.

Wow, I didn't know this. It's still much cheaper to get another titan x than to buy a tesla though

I'd replace the PSU. The Seasonic S12ii isn't a great power supply and not what I would recommend for a TitanXP. Upgrade the PSU then you can run the RX480 for Windows VM. RX480 is still a decent card and should have no issues running GTA V and Train Sim at 1080p as long as the VM is allocated enough CPU resources (cores).
Look at PSUs like the Seasonic Focus Plus Gold (650W+), Corsair RMx (650W+) or Corsair TXM (650W+) as they will have the required PCIe connectors.

It is possible but not convenient. You would need a separate, and preferably not a power hungry video card, maybe some nvidia low end ones, and PCI passthroughing requires a lot of steps. You have also to make sure your IOMMU groups are separate for your PCI slots, IOMMU correctly supported and enabled, dumping the GPU bios, etc.

Did you try https://fdossena.com/?p=wined3d/index.frag to run it it in wine?

W8...Why not just use Lutris which uses DXVK, that is far better than opengl. Also Wined3d is included in the recent versions of wine but is useless since DXVK came out

I tried lutris, but whenever I check the "Use DXVK" option, the game never opens. Unchecking it does allow GTA V to open, but with really weired graphics with overexposure and all.

I confirmed that DXVK dll's are installed in the correct folder(it did that automatically), and the correct version is selected. It just wont launch with that.

Any idea what might be wrong?

That is really strange, are you sure you got the Vulkan loader installed?

apt install libvulkan1 mesa-vulkan-drivers vulkan-utils I suppose, those should be installed out the box btw.

who needs GTA V when you have awesome open sourced games on linux like this one. I love this game. It works with my Logitech f310 joypad out of the box

 

if you really must game....

well, linus can show you around a bit. No GTA support(yet) but witcher 3 seems to run fine.
