Hi all -- I was experiencing this issue in July. There was a spike in latency exactly every 15 minutes (literally every 15 minutes).
Thanks for the report on Uninstalling Support Assist, as that should help some people finding there way here:
We have seen that for a while now over the years. Seems it's depended on various Processes and Services and tends to get overly-needy as it tries to monitor everything.
In another thread, we came across this other software causing Latency or communication problems over USB/Networking ports. Since I think some of yall use external audio interfaces, I thought it might be a helpful troubleshooting step here.
From my notes:
I've found that you can simply uninstall Intel Killer Performance Suite from Control-Panel/Programs-Features, and then reboot . I found that all the Killer/xTend Services were also properly uninstalled (but you should probably double-check for lingering Services anyway). The base ethernet Network Interface Card drivers are left in place and the NIC still works fine (actually, usually better than before as it's a leaner/simpler configuration).
I'd uninstall everything related to SupportAssist (and Killer internet).
Has anyone tried using Process Explorer (free from Microsoft) to see if it can ID the specific process(es) causing the excessive Interrupts and DPCs?
Launch PE and select Options>Always on top. Make the window small and put it off in a corner of the screen. When you notice lags, look in the PE window to see if it can ID the specific process...

I'm also having disaterous incidents of DPC Latency. And I do believe it's related to the NVIDIA GeForce RTX 3060. How did you get rid of the NVIDIA control panel?
No. Please look elsewhere (lots of good tips in this thread and others here).
No, don't get rid of the Nvidia-CP either (you need it).
Remember, many use Nvidia RTX-3060 and similar cards for VR, gaming, and other low-latency uses.
