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.
