Windows 10: Continued Microstutters

I've included my Latency Monitor report. Please help me as this has reduced this computer's effectiveness by half for my uses and it was not like this a few months ago. I've raised it back from BSOD with USB boot device and then redone Windows 10 with refresh or whatever. After that I made some streamlining changes following instruction from online on powershell. Nothing is completely taking the stutter away and its critical a quarter of the time. Its just lessened. I'm sorry if I don't know all the technical jargon but I would invite you to check out the LatMon report. Thank you and good night.

CONCLUSION
_________________________________________________________________________________________________________
Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. 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 0:00:32 h:mm:ss on all processors.

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. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.

Highest measured interrupt to process latency µs: 853.90
Average measured interrupt to process latency µs: 19.919237

Highest measured interrupt to DPC latency µs: 827.20
Average measured interrupt to DPC latency µs: 10.548471


_________________________________________________________________________________________________________
REPORTED ISRs
_________________________________________________________________________________________________________
Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.

Highest ISR routine execution time µs: 259.423913
Driver with highest ISR routine execution time: ntoskrnl.exe - NT Kernel & System, Microsoft Corporation

Highest reported total ISR routine time %: 0.022480
Driver with highest ISR total time: ntoskrnl.exe - NT Kernel & System, Microsoft Corporation

Total time spent in ISRs % 0.028052

ISR count execution time <250 µs: 6030

_________________________________________________________________________________________________________
REPORTED DPCs
_________________________________________________________________________________________________________
DPC routines are part of the interrupt servicing dispatch mechanism and disable the possibility for a process to utilize the CPU while it is interrupted until the DPC has finished execution.

Highest DPC routine execution time µs: 12708.394022
Driver with highest DPC routine execution time: ACPI.sys - ACPI Driver for NT, Microsoft Corporation

Highest reported total DPC routine time %: 0.080094

DPC count execution time 1000-1999 µs: 2
DPC count execution time 2000-3999 µs: 3
DPC count execution time >=4000 µs: 0


_________________________________________________________________________________________________________
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: svchost.exe

Total number of hard pagefaults 24
Hard pagefault count of hardest hit process: 10
Number of processes hit: 8

Microstuttering and sound popping

Since installing the latest feature update for Win 10, I've had an issue with frequent microstuttering. The fps drop is basically imperceptible, I need to be running an FPS counter to notice it. But the sound issue is egregious. I'm used to some microstuttering running games on laptops, depending on the game. Usually it'll occur when loading a new asset. But here, it's not just games and it impacts the sound. It can happen minutes or seconds apart, feels quite random. It does not seem to be bound to anything going on that I can see on the task manager - it can happen with very low disc, memory and CPU usage. And it can happen when I'm just watching video on VLC. So I have no idea what to do about it, any suggestions?

Phenom 9850BE low voltage overclocking results!

well if your going to continue with overclocking, i suggest doing the baby steps thing heh. good luck with the overclocking

 

Microstuttering masterclass

That's it, I'm gonna strangle someone! erocker, give me your home address and telephone number and we'll arrange that showdown! *Laugh :laugh: j/k

It's sort of the first option, but it's not making a statement about any particular system. I simply ask if you've seen the effect (doesn't matter where) then how much does it bother you.

I noticed that no-one "kinda likes it" lol.

I think the question is clear, but if you think it should be rephrased, I'm open to offers. *Toast :toast: In fact, reading through the thread, quite a few people have suggested different poll options, so feel free to rejig it!

If it is rephrased, then I suggest that all the votes be cleared.
