Nvidia tried so hard to stop this - GPU Sharing with Virtual Machines

Is this the solution to the chip shortage? Using Windows paravirtualization and a some custom scripts makes sharing your GPU power easier than ever.

If they had really cut that GPU in half they could probably still re-sell both halves for higher than the MSRP given the state of the world right now.

[TroroXeroZ]

Finally! I've been longing for this guide for some time now.

[simfoo]

The more interesting setup would be to have Linux running as the host and split & share the single GPU with a Windows VM

[bpkdasbaum]

I use Aster Multiseat Software for to do the same thing. Creates up to 8 Virtual Machines / Individual Window Logins. Much easier setup. Used it for Multiboxing in WoW, GF PC and Bedroom TV. Have 8 Monitors on 2 graphic cards. The main graphics card was running 6x windows/wow.

[kamalot]

Would you be up for a follow up video where you do testing with this on a few different cards like say the 3050, and maybe more likely to be owned kind of cards?

[tilgare]

I literally watched this video once the day it came out, and it was just a cool oddity. And then Anthony 2 weeks later throws it over with a suggestion of a gaming couple's machine and I'm back over here watching again wondering if I somehow hadn't watched this video. It makes so much sense to build a monster PC with a 3090, even splitting the VRAM you still have 12GB for both sessions, effectively a 3080 each. I'm really honestly considering whether the performance of half a $3000 PC is possibly better than that of 2x $1500 PCs, or even 2x $2000 PCs? You can add a LOT of grunt to one PC when you're not buying 2 CPUs, 2 GPUs, 2 Mobos, etc.

[Master_Ed]

Wow I haven't heard the illuminati confirmed tone in such a while, nice to hear it in this vid

[TheAzureLance]

Correct me if im wrong, but werent you running two VMS at the same time? So you cant expect half the performance of a single system. You are running 3 instances of windows. The host machine + 2 VMs. And the GPU is still being shared between 3 systems, the host and 2 vms. So i dont think the performance is too far off of running it in a single system.

[asktoseducemiss]

Imagine you want to play a round of that game and having Linus testing his VM on your team.

[pieterrossouw]

I was all into virtualizing my gaming PC until I learned how much anti-cheat software hates VMs.

[GabrielTobing]

Anti-cheat software: Oh no you don't.

Scalpers: Oh no you don't.

[JarrodsTech]

This would have been great for your "Leftist PC" build, it really is our GPU.

[troger]

To share a GPU with friends, it requires two things:
1) a GPU
2) friends




I only have a GPU

[damienr]

this might be an interesting one for households with a kid or two kids that are looking to move from console to pc. Having a hub pc for the household is an interesting concept.

[everope]

Sharing the cost of 1 top tier GPU with the boys would definitely be easier and cheaper than finding 4 mid-range GPUs

[CraftComputing]

Or you could do what I did, get a 64-Core Epyc Rome, 256GB of DDR4 ECC, 3x Titan X Pascal and 10 1.2TB Enterprise SSD to run 12x Gamers off one rack mounted system. Awesome video Colin (and Linus). This tech is incredibly powerful for distributed computing, and I can't wait to see what the future holds.

[elerivalduke]

I feel that as a kid linus' experiences with being broke and wanting to game coupled with his experience as an actual company owner has really helped his want/need to get around arbitrary bs like this, it's really really solidly good for gamers.

[Vloodzy]

Linus' GPU is so big, he has decided to split it to 2 and share it with others.
Such a generous man.

[joehelfrich]

How many takes did Linus need to keep a straight face during "definitely don't just spin up a new one whenever your license expires."

[AlejandroGG]

I think it's worth mentioning that some anticheat software (Vanguard, etc.) rejects running the game they are bundled with in a VM. Maybe there are workarounds for the particular game, maybe not, but don't expect to be able to play every AAA competitive game with this setup.
