Windows 10: Windows 10: High DPC latency ndis.sys

Recently, my audio has been crackling and popping and glitching, and I wanted to see what the fuss was all about. I tried everything. Until I found out that my DPC latency was dangerously high. I ran it through the DPC Latency Checker and LatencyMon, and apparently the problem was "ndis.sys". I've literally tried EVERYTHING. Here's a list of what I've done to resolve this problem:

• Updating drivers
• Changing the power plan
• Disabling the dynamic ticking
• Updating the graphics cards drivers
• Disabling Firewall
• Disabling IPv6
• Uninstalling Bonjour
• Disabling Energy Efficient Ethernet
• Disabling/re-enabling drivers
• Adding PerfLevelSrc, PowerMizerEnable, PowermizerLevel, and PowermizerLevelAC values to Registry Editor
• Uninstalling antivirus software
• Modifying the "Start" value in the Registry Editor's value to 4

UPDATE: Recently, the DPC latency has declined, which is good, however it still sometimes has latency-spikes and I still don't have proper DPC latency.

Windows 10 DPC latency issue with ndis & tcpip.sys

Your code and my recent
CrazyPingTest3 trigger DPC latency issue of tcpip.sys after a couple of runs. Like you said.

One run of your code, one run of CrazyPingTest3 or infinite run of my infinite pings (original
CrazyPingTest) cause just 0.5 to 1 ms latency.

But! If I add a 50 ms sleep before starting a new thread, there is no latency at all. See my
CrazyPingTest3). There is a commented line.

And if I add Thread.Sleep(50); before your

p.SendAsync(ip, 1000, ip);

I see no DPC latency too.

And thank you for the link!

Upd. Oh, I was wrong. I made some more runs and had a DPC latency.

And I’m here because of “windows 10 ndis high dpc” issue too.

Windows 10 High Dpc Latency

I believe DPC Latency Checker does not support WIN 10. Please try LatencyMon and check.

I had this issue so thought of sharing.
