Has anybody successfully linux-gamed on proxmox VE?

I'm extensively looking to setting up gaming on linux inside a VM on proxmox VE. But nothing i've tried worked.

I'm trying out bunch of games through Steam and its proton compatibility layer. Games I tried:

I've tried:

on VM:

I was successfully install Windows 10 inside a VM and run games on there. By following this reddit post

But on any linux VM attempts, games can go 'starting' but back to 'launch' in a few seconds. It just fails...

I just want to know if anybody has ever successfully done this:D

I've passed through my GPU for acceleration purposes which has worked pretty well. I don't see a passed-through GPU in your screenshot. I'll assume you turned on the correct IOMMU and SR-IOV settings, added the PCI:E hardware to that VM, and made sure it showed up inside the guest OS?
- Yup! The screenshot can be confiding because I tinker a lot with cpu, memory, pcie etc. I made it work with gpu pass through etc. so it was hard for me to capture exact setup in a single screenshot. in fact, games that don’t require proton runs very well like Celeste.
Are you passing through a GPU? If so, are you sure the proxmox host isn't using it?

Edit: Just saw the link in the post was to a GPU passthrough guide, so better question, do you see the GPU from within the VM?

I've admittedly never tried gaming on a linux VM or LXC in proxmox, but I've done other tasks that required GPU hardware acceleration with no issues with both.
Don't know much about proxmox, but I know that Hyper-V tries to create every VM with Secure Boot turned on, and every Linux distro I've tried won't boot the installer like that.

Maybe double check the settings of the VM.
