Hello,
I am quite a noob with linux / proxmox and made a few KVM including a win 10 gaming machine with GPU passthrough. Unfortunatly for me, this machine is very slow/laggy and cannot really be used to play. The performance are a worse than on my 6 years old laptop.

novabench gaming machine : https://novabench.com/view/2576196
I have read as much as I could on this problem and on the setting of this kind of virtual machine, tried differents settings but couldn't find a solution. I am using parsec to connect to the machine.
I mainly used those tutorials to make the GPU passthrough
https://github.com/lucduke/proxmox/blob/main/3-vm-gaming.md (in french)
https://3os.org/infrastructure/prox...virtual-machine-gpu-passthrough-configuration
Here are some informations on the proxmox server and the virtual machine:
Proxmox machine configuration:
the args are for a game that won't work otherwise but I am not sure that they are all needed
I have actually no idea how to solve this, so can anyone help me on fixing this problem ?
Thanks in advance
