[libvirt-users] Performance of guest

[Allence]

I recently used Linux in VMware, but I discovered that kvm can replace it, so I created the kvm environment and then started a window on the host system.
But when I use it, I have a problem. My guest's performance is not very good.
For example, when I use Windows without kvm, the “lol” fps is 160, but my guest is only 135.
why? I only have one guest
what is the reason?
What can we do to promote my performance?
There are my some settings for me.
timer: hypervclock
cpu: 8 socket(intel@ core i7 7700k)
memory: 16G
GPU: 1060
network: virtio


my environment:
libvirt: 4.2
qemu: 2.12
windows: windows 7
host: ubuntu server 1604


If you need my detailed settings, please let me know.
