maybe you will get an answer if you provide some more information.
OS, Kernel and VM configuration?

I have since created a fedora VM with the card passed thru performance is perfect, also swapped out the 6600xt for a 6700xt(amd edition). Same result, fedora VM performance is great Win10 VM is getting 30fps in superposition 1080 medium (6700xt). Funny thing is if I swap the 6700 xt for my vega56 win10 VM performance is great. Rebar is off in bios.

i believe this was the problem, this was required in my cionfig

" feature policy=‘disable’ name=‘smep’/>"

The libvirt xml file I attached DOES have the above line, but it wasn`t the file I was using - it was a backup for my windows VM
