Hi again all
[... special thanks to Repair & Restore for helping! .... I always like a little help (I'm not getting any younger) ]
I'm guessing you disabled the wireless when troubleshooting? There does seem to be a driver stew brewing in the network drivers. The Intel 82583V Gigabit Lan's driver seems odd... can you remove it, and let Windows 10 reinstall it automatically? The ndis.sys issue has been slowing systems for a while now, I'm hoping Intel has a recent version that might fix things.
For the audio drivers, can I guess that you have both the AMD onboard audio & a Creative X-Fi card? I think the trouble might be in the audio driver mix, rather than a DPC Latency issue. For example, you have a recent Microsoft audio driver, hdaudio.sys loading and running OK, a recent AMD HD audio driver atihdwt6.sys in an error state [possibly since I believe you have the AMD HD Audio device "Disabled" in Device Manager], the digital output drivers (HD S/PDF devices) are disabled, and the Creative drivers show a mix of one 32-bit version and some 64-bit drivers....
You might remove all those audio devices & see what shows up when Windows 10 tries to sort them out. (You can always reinstall the latest full version drivers later, if you want).
Your latency trace looked pretty good, surprisingly. The highest latency during the trace was from your antivirus, Bitdefender. I noticed you have a Windows Kit installed. If it's the Windows 10 version, and you have the Windows Performance Analyzer, you can pull up this same graph using that tool. Here's a screen-shot of your DPC Latency during that trace:
