ELI5 if possible, thank you :)
GPU passthrough works pretty well these days, but anticheats will detect you running inside a VM. Evading anticheats detection is a separate issue unrelated with gpu passthrough, usually involves getting the vm to look like a real hardware as much as possible (e.g. using real mac address, hiding kvm hypervisor signature, etc). It’s quite a deep rabbit hole and I haven’t actually tried it.
For me it works very well,
see my comment here:
https://discuss.tchncs.de/comment/8950112However I don’t play anything with kernel based anti-cheat, so can’t vouch for that
Looks like this would run Photoshop even better than my insane hacky wine setup too :')…
I guess a good followup would be, is there a tutorial for Fedora39 / Wayland / Nvidia that doesn’t just inevitably nuke my system :)? I have an intel cpu/gpu in additional to my main card.
Also, if it’s in pass-through mode, how would one set up the card for a game natively in Linux? (plenty of Steam games already run well on the card and I’m worried that this passthrough will run into issues of everything using the shitty intel gpu by default)
It does run Photoshop smoothly on my setup :)
Back when I did my setup,
there wasn’t a clear guide on the matter though, and it was rather hard to setup.If you’re interested, I can link you all my bookmarks on the matter which I made back then though, however none of them were for Fedora / Nvidia specific.
For the pass-through mode,
I use VFIO (Virtual Function Input Output) with kernel / grub configurations, to always dedicate one of my 2 GPUs for the KVM (Kernel Virtual Machine).You’d be looking for hot-plugging/hot-swapping your GPU instead, to un-attach your GPU from Linux and re-attach it to your Windows KVM when it boots.
Back when I was setting up my system, this was not possible on AMD yet due to a bug (Can’t vouch for Nvidia or if the AMD bug is fixed by now though)Please share them and any tips you found along the way! Would be great to have an easy way to use photoshop like this
Here you go, hope these sources will help :)

Legend. Thanks! Down the rabbit hole I go.
Good luck! :)
You need a GPU for the host, to passthrough another GPU to the VM.
You could use integrated gpu like intel cpu, and then a dedicated gpu passed through to the VM
You can “unplug” your unique/dedicated GPU to plug it into the VM upon VM startup. But it’s a bit harder to manage. It’s an option though 👌
Be careful with changing components after you redirect one, it’ll change the IDs and mess things up. I tried once and the IDs kept changing so I gave up. I might try again some day when I’m feeling masochistic.
Is that the you know what kinda train this is kid from polar express?
