Hi Nuno,

NVIDIA should to be in the same shape as AMD on CURRENT since [1]. I'm going to
MFC it soon to land it in 15.0. This means: some users are reporting a working
setup for Windows and Linux guests, however it's not tested very well yet. So,
it's an experimental setup which might fail sporadically, on heavy load or long
time testing.

Note that QEMU does implement some additional quirks for NVIDIA cards [2]. None
of those are implemented in bhyve yet. However, most of them seem to be related
to older cards.
