PDC latency problem

   Hello people,

Forgive me, but I am almost desperate. My system is suffering from DPC latency wich causes popping audio and stutter in YouTube video's. I've tried several things but I can't get rid of the high latency.

First of all my setup:

Motherboard: ASRock Z370 Extreme4
CPU: Intel Core i7-8700K
GPU: MSI Geforce GTX 1070 Ti Gaming 8G
RAM: 32GB G.Skill G.Skill Ripjaws V F4-3200C16D-16GVKB
Soundcard: Creative Sound Blaster Audigy Fx

My sytem operates on Windows 10 Home 64-bit version 20H2

I don't know when the problem started, I just noticed some popping in audio when I was playing MP3's on my system. At sime time it became annoying and I thougt that it was due to a bad harddrive. Moving the MP3's to another drive however didn't gave any improvement.

I am a amateurphotographer as well and I also noticed that at the timne when I export some photo's from Adobe LR to Photomatix (the HDR software that I am using), the whole system stutters. If a YouTube clip is playing at that time the video freezes (sound and picture) and the cursor of my mouse stutters. LatencyMon is showing that at that moment the Nvidia driver shows a very high latency.

After some searches on Google I found out that the audio popping was due to a high latency. I installed LatencyMon and there I saw that nvlddmkm.sys and dxgkrnl.sys were showing very high latency. After some further more Googling I read that these drivers don't necessarily have to be the real cause of the latency problem.

What have I done so far? Uninstalled all Nvidia drivers and did a clean install with only the necessary Nvidia driver. I did a clean Windows 10 install. I turned of the onbaod soundcard, uninstalled teh Realtek drivers and installed a seperate Creative soundcard. I have pugged out all of the USB devices and USB PCI cards. I replaced the 1070Ti GPU by a 1050. Nothing helped so far and my system keeps a high latency problem. Just when I think that I found it another driver shows up with a high latency (ndis.sys for instance shows up regularly).

I am out of ideas and hope that some of you do have an idea or a tip where to look for the cause of my latency prolem.

With kind regards,
Erik
