MagicAndre1981, it's really cool that you are helping people here :-)
I've started getting problems with high DPC Latencies lately - when I listen to music my sound gets interrupted about every 30 seconds and that sucks really hard. I've followed all the instructions here and I've also googled a bit and tried some other things. So here are my findings:
I've got Alcohol 120 % installed and when the sptd.sys driver (which is installed with Alcohol 120 % and also with Daemon Tools) is loaded, the Windows Performance Tools kit shows an "Unknown" module which makes lots of DPCs. But when I disable the sptd.sys driver via these instructions
I get other results - and it seems that the issue is related to my network adapters. If you look at the screenshots, you'll see that tcpip.sys makes a peak DPC of 90ms.
I've got LAN, WLAN, two virtual adapters installed by OpenVPN and one virtual adapter installed by VirtualBox. I've updated both the WLAN and the LAN drivers to the latest version. When I disable sptd and all of the network adapters, the problem is solved. Even with sptd enabled and all of the network adapters disabled there seem to be no problems.
However, I'd like to be able to surf the net and listen to music simultaneously...
It would be great if you could look into this. I'll only attach the screenshots at first but I can also upload the .etl files if you need them.
Here is the version with sptd disabled and all network adapters enabled:
Number of downloads: 31
And here is the version with sptd disabled and all network adapters disabled:
Number of downloads: 27
PS. I've also made logs with sptd enabled but these seem to be more helpful.
