Yeah basically pay a subscription fee... :(
Warp? You shouldn't need that. I run Parsec on a passthrough'd GPU in Windows 11, works great.
Ok so how do i do the same but with other VM's? possible?
Well, you can only passthrough the GPU to one virtual machine at a time. And you have to make sure that you don't over-allocate resources (CPU and RAM) to your running virtual machines. But now that you have Proxmox running, you can play around with tons of different stuff!

There's nothing special required. You just need to make sure that under host settings you're capturing the display connected to the passthrough'd GPU.

Parsec:
"Almost 99% of 15000 errors are caused by having either an old, a low end or a cloud server GPU that does not support Parsec. The other 1% is caused by not updating your drivers, or using automatic methods instead of manually searching for drivers from intel.com, amd.com or nvidia.com. If your graphics card does not support Parsec, you cannot host."

Sorry, I don't have any direct experience with this type of problem. I would start a new thread on the forums, someone should be able to help you.

A quick Googling came up with this page: https://www.reddit.com/r/Proxmox/comments/qil7qy/unable_to_pxe_boot_uefibased_vms/

@nick.kopas Hey! i repeated everything with RX 6600, starting VM NOW! ;)

PS 6600 has actual encoder (using RX6500XT for another OEM build with 11700F) pure CPU workloads. no GPU drivers.

Additionally Proxmox VE 7.2-3 works on VEGA2 RX 6600 :)

Just wanted to chime in that this post helped me finally get gpu passthrough working on my AMD Ryzen 7 with RX6700XT build on a Windows10 VM. The tip about turning off resizeable bar in the bios is what did it for me. Along with the hook script I believe. Man.....the amount of times I rebuilt my proxmox server and the number of reddit posts I went through prior to this was nuts and there was not one mention that I could see regarding turning off resizeable bar.

Huge thanks to Nick Kopas for assisting and enlightening noobs such as myself. Couldn't have done it without ya!
