See https://bbs.archlinux.org/viewtopic.php?id=162768 first post. See if you
need ignore_msrs or allow_unsafe_interrupts. I had similar issue with and board
and some module options fixed it I think.

Check to see if you have MSI enabled. That'd be my bet. Alex had a blog post
that covered it, but I don't have the link handy.

Hi all,
I was wondering if anyone is experiencing this and if there is a known fix for
it.
I am using ArchLinux with latest stable Kernel, qemu and libvirt.
My CPU is FX-8230 with a GTX 970. I've passed thorugh the GPU to a Win10 guest.
In WoW on bare metal i get 90 fps and in the same area with the same graphic
settings on the VM i get around 50. There seems to be no cpu and or ram
bottlenet and the GPU seems to be quite gully used since the fans are starting
to spin quite soon.
Can anyone help here with a suggestion? I saw reports with about 3% performance
drop, but I am experiencing a lot more.
Thanks!
Andrei.
