well, yes. My first configuration was without cpu pinning and I had worst
performance.
I've attached a monitor on the vm to see real performance and it's really
low...I've gained some fps but far from what that card can do.
King of fighters 13 bare metal 60fps , vm 32 fps.
Tried right now removing cputune section from xml and stopping nearly all
services that were running on the machine.
With there performance, I think neither a fresh installation would be good
for performance.
