You are not alone. I have had the exact same symptoms. Wanted to
build a "gaming" machine with two seats for playing Heroes of the
Storm. Performance was bad. Very low fps especially in fights. No
difference between low and high graphic settings. <br>
<br>
Nevertheless, graphic benchmarks, like 3D mark, certified a very
good GPU performance: [1] VM, [2] Native (Yes, the VM performs
slightly better). There, you can also see my system specs. I suppose
this is some kind of CPU scaling problem in HotS. :-/<br>
<br>
I'm very interested if you can actually find a solution :) Good
luck!<br>

<p dir="ltr">StarCraft and
heroes are the two games
that have this problem, they
are both based on the same
engine. Unfortunately I
cannot test the cpu because
if I were to change my cpu
to anything but "host" my
machine will not boot (I
believe this is due to a
problem with the AMD
drivers).</p>
<p>I believe the MSRs are
called by Windows 10, since
they are privileged
registers. Likely for
debugging purposes here.</p>
<p>I would suggest trying
something more related tou
your cpu ("Haswell" in my
case) instead of "core2duo".
I remember when I first
tried to install Win10 under
virt-manager I got a KVM
error about unsupported cpu
functions when I tried to
clone the host cpu. Setting
it to Haswell cleared those
errors so this might have
something to do with it.
Unfortunately that didn't
play nice with my video card
so I ended up with a command
line setup as virt-manager
setup refused to load AMD
drivers.</p>

<div dir="ltr">I
have a pretty
stable VFIO
setup running
for a while,
but I am stuck
with this
<div>odd
problem where
1 game (heroes
of the storm)
keeps giving
me a BSOD</div>
<div>whenever
I try to run
it in the VM
under Windows
10.</div>
<div><br>
</div>
<div> All
other games
are running
fine. If I
install
Windows 8 in
the VM the
game runs
fine.</div>
<div> If I
boot the
machine into
the Windows 10
HDD directly
the game runs
fine. </div>
<div>This
crash occurs
with both
Nvidia GTX 770
and AMD Fury
X.</div>
<div>It only
crashes when
in VM and
Windows 10.</div>
<div><br>
</div>
<div>The BSOD
is some form
of exception.
Examples that
occur</div>
<div>SYSTEM_SERVICE_EXCEPTION <br>
</div>
<div>KMODE_EXCEPTION_NOT_HANDLED<br>
</div>
<div>SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M<br>
</div>
<div>The dump
files seem to
suggest a
windows8
driver issue,</div>
<div>but I
can't pinpoint
any faulty
driver.</div>

</div>
<div>I am
running
netrunner
(manjaro)
kernel 4.4.9,
qemu 2.5.1.</div>

BSODs are
often the
result of
calling an
unsupported
MSR and not
handling the
exception.
There's some
risk to this
option because
zero isn't
guaranteed to
be a valid
return for an
unknown MSR,
but it seems
to solve a lot
of problems.
YMMV.</div>
