I am having the same DPC issues that many others are having, up to 500ms DPC's on ndis.sys. I followed the instructions here: Video STUTTERING, Audio CRACKS/POPS and dpc/isr LATENCY (posting instructions)
Attached are the trace and sysnative dump (I ran as administrator but it still said access denied for most items...): Trace+SysnativeFileCollection

My best attempt at answering the following:
- Write a brief description of your problem.
You can also include the steps you tried. - High turnaround time on ndis.sys causes audio and visual stuttering. I have factory reset with a fresh installation of Windows and still the problem is present. I have tried disabling Avast, turning off all power saving options for my network adapter, updating all drivers/BIOS, running TCPOptimizer, scanning for viruses/corrupted files, scanning my RAM and SSD, and a few more things (problem has existed since mid-November).

- 64 bit
