I've recently tried to do that using sunsine and different linux gaming distros and it was awful, the VM was working great for a few minutes and then suddenly crashes and I have to hard stop it.
All the people that I've seen talking about it on the internet are using Windows VMs so I guess that I'm doing something wrong or the only way to do it is through a Windows VM, which I'll not even try.
Are you running this with something like libvirtd/qemu? If so, VFIO configurations can get pretty complex. Random crashes seem like MSI interrupt issues (or you've allocated too much RAM to the guest). Or it could be GPU reset issues that would also occur on the (Linux) host, a newer kernel and Mesa version in the guest may help.
Setting on the kernel commandline for the host to workaround MSR interrupt crashes:
If you're running on a Windows host or with something like Virtualbox (assuming GPU passthrough is supported by these), YMMV but I wouldn't expect good results.
I'm using Proxmox with an NVIDIA 1050 GPU that I was passing through to another VM for jellyfin transcoding in docker (I don't need it anymore), because of that I thought that the drivers were set up correctly.
The guest was Bazzite with 2 cores and 2 GB of RAM, I was not even gaming, just login on steam and updating the system and I had sudden crashes with Bazzite only using 1 GB on the Summary...
Ah Nvidia. Bazzite uses Wayland I believe since it uses the same gamescope session as SteamOS (unless something has changed recently). While it may be possible to get it working, I'd expect a much better time with an AMD card.
A traditional distribution may be a better bet with Nvidia for now.
Thanks, I've also tried to change the autologin with x11 with no success, I'll try with nobara, but I really liked the console-like features
