Stuttering Issue

[Candril]

Hi, I have been having this issue for over three months now and tried all the fixes I can find for stuttering, turning off a lot of unnecessary windows 10 features etc but nothing seems to fix it, I had an issue with 100% D drive usage that I tracked down to the PCI driver bug and changed the setting in bios from 1 to 0 which fixed it for a few weeks, when it came back I tracked the issue down to D drive being my page file and when swapping it to my SSD it stopped the 100% drive usage, I am unsure if this a connected or separate issue and if that drive is dying, crystal disk info shows it as good as does seagates seatools and it passes all the tests and CHKDSK says all fine, a week ago it started double clicking after inactivity but that stopped after doing that for about 30 minutes.

 

Using Latency Mon yesterday I had very high ISR from DirectX graphics Kernel and very high DPC routine execution time from Nvidia graphics driver when loading and playing the newer CoD modern warfare game, stuttering is most pronounced in this game so have been using it to test changes but stuttering is present in all games whether installed on my NVME or my HDD, I did a Windows 10 repair install a few weeks ago to no success, today I cannot get my system to repeat the very high ISR and DPC counts in latency mon and did not save my results yesterdays but  I will paste todays results if that helps at all.

 

Yesterday I swapped my 970 gtx out for my older MSI 660 GTX, no difference in Modern warfare but Escape from Tarkov seemed a lot smoother despite having half the amount of VRAM as my newer card on the same settings.

 

I have also disabled AMD SMT hyperthreading in bios as know this can be a cause of stutters which has not helped, I have also swapped put SATA cables for new ones, tried different SATA ports and unplugged and reconnected all cables giving connectors a blow, used different power connectors for HDD and dusted the case thoroughly, I have ran my memory at 2993, 3000 and 3200MHZ with XMP on and off and all seem to give the same performance to me.

 

I am at the absolute end of patience with this stuttering, I have spent a good 100 plus hours googling and trying fixed myself to no success.

 

Thank you in advance for any suggestion or help!

 

Edit: The Stutters are every 1-5 seconds and last for a fraction of a second multiple times or are sometimes larger lasting 1-2 seconds where the picture completely freezes.

MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution.

 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.

while not reproducing the latencymon report from yesterday I have just got one where some problems seem to be happening:

 

_________________________________________________________________________________________________________
CONCLUSION
_________________________________________________________________________________________________________
Your system seems to be having difficulty handling real-time audio and other tasks. You may experience drop outs, clicks or pops due to buffer underruns. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates. 
LatencyMon has been analyzing your system for  0:04:05  (h:mm:ss) on all processors.

It’s hard to diagnose a situation like this when there is so much that has been tried.  It sounds like there’s some system or other that is only just barely keeping up with things and any additional issue puts it over the edge.  I’m not sure the actual root cause was ever fixed.  That said I don’t know what that root cause is. 

[Kennoi]

What SATA driver do you have in Device Manager? 

 

Used to have default AMD drivers here, they're not compatible with Windows 10 and always gave me micro-stutters.
