Hello,
Just wanted to mention that I got rid of a lot of the lag by compiling
qemu 4.0.
I dod not know if its a threadripper issue or not.
The lag directly coincides with hard drive access.
No hard drive access, no game lag.
I have redhat virtio drivers installed for the hard drive and the nic.
Are these drivers intel only?
They are left only from my i7-4940mx processor install.

Hello.
I am new to the list.
I have been doing gpu passthrough for almost 5 years now with a i7
4940mx cpu on a msi gt70 laptop.
My new PC build is:
MSI x399 carbon pro motherboard : bios xxxxxx.1c0 : svm=enabled:
iommu=enabled
Threadripper 2920 12 core
Radeon pro duo R9 Fury X
Nvidia 980 TI OC
I was unable to passthrough the nvidia card due to it not getting past
the "Running option rom..." message when debugging.
The Radeon passed through with flying colors.
The issue:
I used the radeon to run triple A games in linux using steam for linux
and proton. No problems.
In Windows 7 in qemu I have passed all 24 cpus to it.
They max out to 80% while playing the same triple A games and the
games lag.
I have never had this issue before.
Admittedly I am using the same script I used on the i7 to get going.
I had to remove threads from the -smp switch and use cores only.
I also removed the kvm=off which is used for nvidia cards.
I am looking for links to articles or direct info on what to do to
optimize the cpus.
When not lagging the radeon performs extremely well.
I am concerned that perhaps kvm is not being used.
Thanks
