I can't reproduce that issue, I tested a Fedora VM with both npt 0 and
1, of course with the same GPU performance results as windows. I've
mailed some AMD guys and KVM guys, and hopefully someone can at least
figure out what is going on. Also, Alex has reproduced this himself on

40fps to 75fps!). However with npt disabled the Windows10 VM slows down an
