Basically the title. I’ve only ever seen huge 20 page guides on how to make it work. Is there an easy way?
Specifically on Debian or Arch with a laptop with two gpus (zephyrus g14)
I also don't know if there's any Linux program that will automatically do the configuration for you.
It seems like it would be pretty complex since I guess you need to disable the linux host from using the GPU, and do PCI passthrough in a VM that has Windows installed.
And there's still the problem of the graphics needing to move around the system in order to get to the display instead of the display being directly connected to the GPU.
Seems like a pretty cool thing that would be neat to have a nice automated GUI solution for.
I was just looking at, seems like it's difficult but not impossible
I'm in the same boat that it seems too difficult (and I bet the performance still isn't near native).
I just dual boot and boot into Windows if I'm going to play a game.

This is all addressed by the Linux kernel and xml code specifying it for the VM.
And there's still the problem of the graphics needing to move around the system in order to get to the display instead of the display being directly connected to the GPU.
Again handled by the kernel and qemu, just requires a bit of XML code in the vm description. Not a big deal.
I have the 2020 G14 and I got this working once. I'm afraid easy and simple are not a thing here, as you need to understand what you're doing if you want it to work well.
The basics are:
- Prevent the host system from loading any drivers that touch the discrete GPU. This is done by attaching it to the VFIO driver and uninstalling/blacklisting the Nvidia and Nouveau drivers.
- Make sure you have the correct kernel parameters to support virtualisation and PCI-e passthrough.
- Create a Windows VM and attach the Nvidia GPU to it.
- Setup Looking Glass so you can play with the best possible latency. This will likely require a dummy USB-C display stick.
Personally, I don't think it's worth the hassle. I keep a Windows install for when it's needed, and do most of my gaming on a separate system.
even with cpu passthrough some things are still emulated. you can run a vm detector and see for yourself what tests fail.
it may not affect your games but others should still be careful since it is a real issue, and people do get banned for it.

Indeed. That’s the opposite of what I’m looking for though. That’s complicated and apparently breaks ?
I’m currently dual booting. Which works fine. I was wondering if there was an easier way though.
With Proxmox on AMD gpus, it can be as simple as picking a pci device from a dropdown.
-- but then again, you'll need to learn how to properly use proxmox, esp. with respect to storage configuration. Also, the performance can still suffer, depending on various factors.
If it's not too big of an inconvenience, dual boot is the way to go, IMHO.
