I tried two PCs and my D525 system has 2mS hits. Unfortunately this program doesn't really aid in finding the glitch. I turned off the sound and not much difference. My AMD quad core has peaks of 200us.

Regarding linux, I've never tried them, but there are hacks to reduce the latency. Google will dig up all sorts of things to try.

has tips for windows and linux.

My concern would be a really bad driver that spikes into the 1,000's
of us every so often. Every once in a great while there could be a
collision. That would really drive you crazy trying to find it.

Indeed, Bob. On a critical system, it might be best to establish a
baseline for DPC when you first install the OS, and then note any
changes as extra devices are installed. You would be unlucky to find a
bad driver in the base OS install, although it's possible.

Cheers,
David
