GPU Passthrough to Qemu Win10

Hi,

I have some questions about GPU Passthrough to Qemu. I have no fails, but it wont work.
I checkout this tutorial  [https://wiki.archlinux.org/index.php/PCI_passthrough_via_OVMF ]

My System  Intel i7 6700K and AMD RX 480 GPU

Of course i have connect my display to the internal GPU  big_smile

Hoffe mal das jemand eine Idee hat was ich machen kann damit die Grafikkarte in Windows  richtig erkannt wird

My System Infos and configs and a Picture of Device Manager from Win 10 follwing.

Thanks all for an answer
