[SOLVED] Extremely High Latency

[rauvel]

Got a new laptop recently, it's a Lenovo Ideapad Gaming 3, but i'm getting random freezes and audio is popping
I used latencymon to see what's going on and i'm getting extremely high levels of latency
_
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. Also one or more ISR routines that belong to a driver running in your system appear to be executing for too long. At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results. 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 0:11:37 (h🇲🇲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): 420227.60
Average measured interrupt to process latency (µs): 55.763570

Highest measured interrupt to DPC latency (µs): 420223.50
Average measured interrupt to DPC latency (µs): 46.648393


_
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): 33685.626594
Driver with highest ISR routine execution time: HDAudBus.sys - High Definition Audio Bus Driver, Microsoft Corporation

Highest reported total ISR routine time (%): 0.008110
Driver with highest ISR total time: Wdf01000.sys - Motor en tiempo de ejecución del marco de controlador en modo kernel, Microsoft Corporation

Total time spent in ISRs (%) 0.013960

ISR count (execution time <250 µs): 91359
ISR count (execution time 250-500 µs): 0

ISR count (execution time 1000-2000 µs): 2
ISR count (execution time 2000-4000 µs): 13
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): 95914.540073
Driver with highest DPC routine execution time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation

Highest reported total DPC routine time (%): 0.076425
Driver with highest DPC total execution time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation

Total time spent in DPCs (%) 0.214949

DPC count (execution time <250 µs): 1135439
DPC count (execution time 250-500 µs): 0
DPC count (execution time 500-10000 µs): 260
DPC count (execution time 1000-2000 µs): 45
DPC count (execution time 2000-4000 µs): 324
DPC count (execution time >=4000 µs): 1170


_
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 45023
Hard pagefault count of hardest hit process: 14298
Number of processes hit: 134

[Colif]

it could be this - https://www.amd.com/en/support/kb/faq/pa-410

new bios coming out after May might fix it.

looks like what I get

have you updated drivers? https://pcsupport.lenovo.com/us/en/...ng-3-15ach6/downloads/automatic-driver-update

 

[Lutfij]

Using your laptop's serial number, on Lenovo's support page, see if you're able to get a bespoke support page meant for your laptop. From there see if you have any BIOS updates pending.

 

[Colif]

the bios to fix the stutter problem won't be out until May as per AMD. It is possible an earlier update may fix it.

link I showed is for laptop auto update page

 

[rauvel]

I read about the amd problem before, but the weird thing is that the laptop works fine from time to time, a restart sometimes fixes the problem. The drivers are up to date according to https://pcsupport.lenovo.com/us/en/...ng-3-15ach6/downloads/automatic-driver-update

 

[rauvel]

Any temporal solution? I use this laptop for my classes 😓

 

[Colif]

my experience with stutter is it only happens sometimes, if yours is more constant it could be something else.

I don't like how they renamed the driver packages so I can't tell what you actually have

Highest ISR routine execution time (µs): 33685.626594
Driver with highest ISR routine execution time: HDAudBus.sys - High Definition Audio Bus Driver, Microsoft Corporation

that could be AMD or Realtek.

your DPC being DirectX could be audio or GPU
Page file usage - MSMPENG is Windows Defender so could be lan, or could be defender just runs a lot.


Can you download and run Driverview - http://www.nirsoft.net/utils/driverview.html

All it does is looks at drivers installed; it won't install any (this is intentional as 3rd party driver updaters often get it wrong)

When you run it, go into view tab and set it to hide all Microsoft drivers, will make list shorter.

take a screenshot from (and including)Driver name to (and including)Creation date.

upload it to an image sharing website and show link here

 

[rauvel]

I'm not sure how to add an image here, but here is the link
https://freeimage.host/i/M0ZOiu

 

[Colif]

i should have shown a link for images, and that site wouldn't have worked with instructions anyway

well, your sound drivers are newer that what I have.
it is realtek
all of it. Ethernet and WIFI are realtek too..
do you use wifi or Ethernet cable?
WIFI dated 6th Sept 2021
ethernet 16th Nov 2021

ethernet drivers
download Win11 Auto Installation Program (NetAdapterCx) from under windows header here - https://www.realtek.com/en/componen...0-1000m-gigabit-ethernet-pci-express-software

WIFI might take me a while. Different chips have different drivers

shame its not a thinkpad - https://support.lenovo.com/au/en/do...for-windows-10-version-1809-or-later-thinkpad (don't use these, its right chip. wrong device, so close and yet...)

seems wifi can cause the stutter - link

you may have to wait for lenovo to update the driver for your laptop

 

[rauvel]

rn i'm using WIFI

 

[Colif]

seems, you have newest drivers according to site, your realtek driver package dated 17th Jan 2022.
the package is new but some of the drivers in it aren't - this is normal. I just can't tell looking at drivers.
https://pcsupport.lenovo.com/au/en/...for-windows-10-64-bit-ideapad-gaming-3-15ach6

So that doesn't help.

so its almost constant?
I wonder if it happens in safe mode

1. go to settings/recovery
2. next to advanced startup, click restart now button
3. this restarts PC in a blue menu
4. choose troubleshoot
5. choose advanced
6. choose startup options
7. click the restart button
8. choose a safe mode (it doesn't matter which) by using number associated with it.
9. Pc will restart and load safe mode

can't play games but this will at least tell me if its a driver to blame.

 

[rauvel]

Let me try that, I wouldn't say the problem is constant because yesterday it was working fine, it happens randomly, there's no way for me to tell specifically how often it happens, but today I have restarted the computer at least 10 times and it persists. I'll try booting on safe mode

 

[rauvel]

No freezings on safe mode, it runs perfectly

 

[Colif]

so how do i figure out which driver is cause...

when you run latencymon, once it gets a result. stop it and look on the drivers and processes tab and screenshot those, just curious what your most used are. I know what report shows. I often see DirectX as top

i don't run it often now I am waiting for bios update. thats an old report above. My highest is part of windows which always helps.

wonder what chipset it has

There you go

 

[rauvel]

Sorry if some things are in spanish, that's my main language

 

[Colif]

Once you get to an error, take screenshot of drivers tab.
lucky the driver labels aren't converted

seems you have realtek and AMD Audio drivers. I wonder how that works.

 

[rauvel]

So i should run latencymon again? How much time? I instantly get a conclusion when running it

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. At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.

 

[Colif]

At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results.

so do you have the option to run via Ethernet and see if that removes one error?

 

[rauvel]

I have the port but i don't have the cable

https://freeimage.host/i/MGKgVa

Here is the drivers section screenshot

 

[Colif]

latencymon self reporting there. its top of list.
ignoring it
ntoskrnl is 2nd but well, its the windows kernel so its got an excuse'
wdf1001.sys is windows driver framework driver - its the one that sits on top on my PC if I get a warning.
ndis.sys - network driver Interface Specification - talks to WIFI/Ethernet drivers
storport.sys - storage port - storage drives
dxgkrnl - direct X
tcpip.sys - transmission control protocol/internet protocol - used for internet (its in the name)
ndu.sys - network driver data usage
afd.sys - ancillary function driver for winsock - windows driver used for lan

everything below there is on 1.0 or lower execution

enough of them are network related to make me think it could be WIFI.

 

[rauvel]

should i try disabling the network adaptor on the device manager? just to see what latencymon shows

 

[Colif]

turning off wifi would perhaps tell you

drivers shouldn't be used if device isn't. Possibly need restart to get them unloaded.

 

[rauvel]

Let me try that then
