Ignore that. The ‘new’ baseline is 1000. A perfectly tuned win 10 or 11 PC will read around 1050 to 1100, in the yellow. Using that as the new zero, track down the cause of the spikes. DPC runs and you see the spikes occurring. If, say, a spike appears every 35 seconds, or whenever you move your wireless mouse, you can start to track it down.

You most likely have one of three culprits: WiFi nearby, a wireless mouse, or some program that starts up with the computer and runs in the background. That could be all kinds of things, so you first go to startup programs and disable them one by one, reboot, and test. If that doesn’t do it, look for Services running that are not by Microsoft and kill those one by one and test. DPC can run throughout and you see the results within a minute. And kill Cortana too, just because.

Do you have a website for DPC Latency Checker?

For me there’s no better place in the band than to have one leg in the harmony world and the other in the percussive. Thank you Paul Tutmarc and Leo Fender.
