I boot my physical ssd with Windows 11 on it inside Proxmox vm with GPU passthrough, but for some reason video playback is bad, It's like slow motion, and sound is choppy. It works perfect in bare metal with the same nvidia gpu. I tried to share more ram and cpu cores, but this can't help. Right now the vm is with ryzen cpu with 4 cores and 12gb ram and gtx 970 gpu. I'm not sure what else to do to fix this?
