[SOLVED] Getting very high latency in latencymon when idle after booting PC

[K1LLSW1TCH1]

Hello ive been having some odd issues i have been noticing in games audio dropouts and some stuttering so i decided to test my latency and the results seem to be some high latency this is taken about 2 minutes after booting up my PC and im not sure what is causing it to be so high.

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 problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.

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): 74121.0
Average measured interrupt to process latency (µs): 24.108148

Highest measured interrupt to DPC latency (µs): 98.20
Average measured interrupt to DPC latency (µs): 1.041899


_
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): 158.991653
Driver with highest ISR routine execution time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation

Highest reported total ISR routine time (%): 0.004332

ISR count (execution time 2000-4000 µs): 0
ISR count (execution time >=4000 µs): 0


_
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): 331.310851
Driver with highest DPC routine execution time: nvlddmkm.sys - NVIDIA Windows Kernel Mode Driver, Version 528.49 , NVIDIA Corporation

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: systemsettings.exe

Total number of hard pagefaults 2156
Hard pagefault count of hardest hit process: 751
Number of processes hit: 31

I am going to further test during game but when playing rdr2 i have tested it before and the levels were high but definitely not as high as shown in the first image

Check your virtual memory to ensure that the amount being used is large enough for 32gb memory, and that the pc is controlling the execution. When you install new graphics drivers do you use DDU uninstaller to wipe clean all previous drivers? . Display Driver Uninstaller Download version 18.0.6.0 (guru3d.com)

Yeah i used DDU to install these current drivers and always do normally if im updating them this is a new build its about 2 months old. What do you mean by virtual memory page file? If so it does seem quite small its system managed and its 2048mb atm

Have you run sfc /scannow?

Yeah i have but i can try that again ive also tried dism commands

Just run it again and getting the exact same result basically after booting https://gyazo.com/a595d2971d90c108ebb0f8109a70c110

sfc said no integrity violations

could it be some of these other things that are showing a high dpc count other than the graphics card driver

What kind of settings for your cpu, overclocked/undercloked at all? Any other programs you run while gaming? What gpu are you using?

One other thing what motherboard do you have?

I have a z790-f gaming wifi and i did have an undervolt but ive just removed that and the issue is still persisting maybe not as bad but im not sure hard to tell really it still spiking up to 1400 upon boot i run ISLC and hwinfo 64 process lasso while gaming. graphics card is 4090 and processor is i9 13900k

 

[Fix_that_Glitch]

It could be simply an outdate driver for hardware. You can go in to device manager, line by line check for any driver update needed. Is your bios, chipset, ime, drivers up to date also?

Before you do all the other things I asked go into bios and under exit reset bios to optimal/original settings and restart pc. See if anything changes.

You will have to reset your xmp settings for your ram to correct the ram speed after reset.

Legit just tried exactly that loaded optimised defaults and just put docp 1 on also have been through all drivers on motherboard website and updated them ive even tried rolling back to what they were previously to see if it was the new drivers

 

[K1LLSW1TCH1]

the odd thing is ive just tested and its fine now like no spikes at all so idk if its just booting it happens possibly it is something happening when im booting and then it was higher because of the undervolt now ive removed it the spikes do seem to be lower i am waiting around 2mins to run it so maybe i need to wait longer idk https://gyazo.com/0f50a61eb39bfc7cd1cc7145cd08e3cd

Yeah its so strange it only seems to happen when i first start the pc i just get these insane spikes and then it calms down but it can go on for like 5 mins plus and then it seems normal again

Are you referring to boot up time waiting for pc to get to Windows or after it boots to Windows it lags? What if anything do you have in start up menu?

 

[Fix_that_Glitch]

You have a screamer of a cpu. You should remove any power restrictions for the cpu in bios. And try setting your Windows power setting to high performance. That should blow the hair back on your pc.

 

[K1LLSW1TCH1]

Are you referring to boot up time waiting for pc to get to Windows or after it boots to Windows it lags? What if anything do you have in start up menu?

Yeah i have changed everything to optimised defaults apart from RAM xmp. Im referring to being fully in windows i do notice a stutter sometimes when the pc starts and i first get into windows but after that everything seems completely normal but yeah if i run latency mon i get these huge spikes for like 5 mins after booting then everything goes back to normal. The only things i have starting up is ISLC (Intelligent standby list cleaner), process lasso and Nvidia control panel. I just played COD MW2 for an hour or so and it was all green when running it and virtually had no stutters in game. The only game ive noticed spikes in latency mon is rdr2 story and that feels smooth apart from the odd stutter here and there if im going into a new area so it might just be a case of ignoring it idk. I just found this post about people with 12th and 13th gen cpus in windows 11 and having a similar issue and saying it could be to do with that but idk seems similar to what i have been having View: https://www.reddit.com/r/intel/comments/10u5amb/1213_gen_intel_windows_11_users_post_your/

Ive just used the bitsum highest perfomance power plan which disables core parking fully and the issue is completely gone like even if i run it on boot there seem to be 0 spikes everything is below 100 and what is even more interesting is even the nvidia driver doesnt seem to be spiking now. So possibly this is an issue to do with core parking in windows 11 or just on 12th and 13th gen cpus.

That's what I figured something was holding back the cpu performance. I don't understand why the motherboard makers have default power limiting settings for the newer cpu's. They whole idea is to make the cpu's as fast as possible. Not so you have to troubleshoot to find out why your cpu is choking during use.The default should be a screaming cpu out of the gates and then have the option to tone things down.
