Hi,

I've used proxmox as my server for long time and I have dedicated RADEON RX6400 for windows vm for media purpose. Before I made it, I read a lot etc. and lastly it successfuly passthrough.
Problem is that when try play game, f.e. cyberpunk, performance's drasticly drop! fps are very low and it's not playable. On resource monitoring CPU is 100% and gpu is bored.
This gpu is not buggy for reset etc..

What i noticed is that when reinstall system and don't update anything, games working fine!! after any update/install dedicated drivers from adrenaline then performance drop. So I create snapshot with fresh installer and from time to time restore it but this not reslove problem.

I have some time ago rx 570 with passthrough and It's working fine with newest drivers for long time... but now have same issues like with rx6400.

It's possible that newewst version of proxmox broke it?

I give up but maybe you have some expirience with that issue?
