Hey guys,
does anyone know, if the new Notebooks with desktop gpu's will work? I
want to buy one with a i7-6700K and a GTX 980.

The CPU has VT-D and VT-X spupport and the GPU should work too.

4000μs-16000μs here, its terrible.
Tried whats said on
https://lime-technology.com/forum/index.php?topic=43126.15
Its a bit better with this:
<vcpu placement='static'>4</vcpu>
<cputune>
<vcpupin vcpu='0' cpuset='4'/>
<vcpupin vcpu='1' cpuset='5'/>
<vcpupin vcpu='2' cpuset='6'/>
<vcpupin vcpu='3' cpuset='7'/>
<emulatorpin cpuset='0-3'/>
</cputune>
I tried /isolcpus/ but it did not yield visible benefits. /ndis.sys/
is big offender here but i dont really understand why. Removing
network interface from VM makes /usbport.sys/ take over as biggest
offender. All this happens with /performance/ governor of all cpu cores:
echo performance | tee
/sys/devices/system/cpu/cpu*/cpufreq/scaling_governor >/dev/null
Cores remain clocked at 4k mhz. I dont know what else i could try.
Does anyone have any ideas..?

I tested again with VM reboot, I found that this time is about
1000~1500μs.
Also I found that it easily get high while hard drive is loading, but
only few times.
Which specs you're using? Maybe it depends on CPU or patches.

If i understand it right, this software has a fixed latency error
of 1 ms(1000us) in windows 8-10 due to different kernel timer
implementation. So i guess your latency is very good.

Thanks for information! And sorry I don'r read carefully at
beginning message.
For my result, I got about 1000μs below and only few times
got 1000μs above when idling.
I'm using 4820K and used 4 threads to VM, also I set these 4
threads as 4 cores in VM settings.
The OS is Windows 10.

Sorry, but how to check DPC Latency?

I just checked on W7 and I get 3000μs-4000μs one
one of the guests when 3 guests are running.

I have brutal DPC Latency on qemu, no

without any passthrought,
my DPC Latency is like:
10000,500,8000,6000,800,300,12000,9000,700,2000,9000
and on native windows 7 is like:
20,30,20,50,20,30,20,20,30
InWindows 10 guest I constantly have red bars
around 3000μs (microseconds), spiking
sometimes up to 10000μs.
I don't know how to fix it.
this matter for me because i are using
USB Sound Card for my VMs,
and i get sound drop-outs every 0-4 secounds
That bugs me a lot too. I also use an
external USB card and my DAW periodically
drops out :(
I haven't tried CPU pinning yet though. And
perhaps I should try Windows 7.
