Hi there
I'm going to copy & paste a note from another post here: it basically says I don't know much about DPC Latency tools ... but I can point to a few things I noticed while looking at gaming systems recently:
Since you are seeing the trouble with simple YouTube videos & such, maybe the too-high frame rate could be something to look at.
And you mention the wdf01000.sys driver ... it seems to be involved as a sub-component of many different input/output devices, such as mice, touchpads, keyboards ... and who knows - maybe your capture card. While we wait for a tech with DPC Latency experience, you could try different drivers for those input/output devices (mice, touchpads, keyboards, capture cards..) ... Good luck!
