Proxmox running on HPE DL380 with GPU passthrough to Windows 10 VM.

GPU is a Quadro P2200. It's detected in Windows without issue, encoding/decoding in Plex occurs without issue.

When enabling the FFmpeg Profile I setup for 4K streaming, the system defaults to the CPU. From what I can see, ErsatzTV can see the GPU and even starts to load something, but something crashes, and I don't know enough about ffmpeg to know what to change. So any support would be helpful

Here is my Troubleshooting > Nvidia Capabilities
