[vfio-users] RX 480 on Windows 10 guest freezes with DX11+ games

[Tomáš M.]

All solved, ASUS returned, bought Sapphire
https://www.techpowerup.com/vgabios/185767/sapphire-rx480-8192-160809

blocked amdgpu, put there the RX480 ids, booted up with same script, did
clean install of drivers (just to be sure) according to
https://community.amd.com/thread/180667 and all works.

I will not touch anything in wattman and probably just use the silent bios.
