Hello,
While watching Netflix, the DPC latency (dxgkrnl.sys) jumps rapidly. The image stuttering when playing in full hd (under Edge).
Youtube 4k in 60 frames per second plays absolutely smoothly, no problem with latency. There are also no problems with the games.
The problem with high latency and dxgkrnl.sys occurs only under Neflix. There are also 'Hard pagefaults' caused by 'msmpeng.exe'.
Fresh installation of Windows 10. Disabled C-States. Latest Intel drivers, Latest Bios. What could be the cause?

REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of
resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.
NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks
and pops. Check the Processes tab to see which programs were hit.
Process with highest pagefault count: msmpeng.exe
Total number of hard pagefaults 4876
Hard pagefault count of hardest hit process: 2333
Number of processes hit: 32
