[SOLVED] DPC ISSUE, micro stuttering

Calcifer · Feb 24, 2016

Hello everyone,
i have an issue with windows 10, since i bought a new pc ( september ) so i have fresh install .
first of all my rig is :

Asrock H97 Pro4
Intel i5 4460
asus xonar dgx
gtx 970 g1
samsung 850 evo 120gb
WD 1tb caviar blue
8gb ram corsair vengeance
xfx 650w pro series (or ts

) bronze
cooler master hyper t4

The problem is i have totally random micro stutter on both audio/video. I really tryied a lot of things :
- updated all drivers
- updated bios
- updated ssd firmware
- put max performance on windows setting power option.
- disabled HPET ( i also tryied to activate it on both bios and OS )

I've read a lot of things about the fact it could be the intel lan driver ( there is a really long post on intel forum about that ). this issue ( ndis.sys and tcpip.sys ) has been " fixed " installing older driver version, 18.3 . though only works on windows 7 and 8 . windows 10 doesn't install those version and if you try it out you wil see 19.3 version. I've tryied using a windows 7 or 8 driver but the problem got worse.
though, uninstalling and disabling it, the problem isn't gone ( but i didn't reboot after i did it , i don't know if that would change ).

the micro stutter occurs really rarely when i watch youtube, listen music or watch video but a lot more often on game session ( i can say on games is guaranted ).
In fact i just have to log in in a game with latencymon On and just, i don't know move camera or wait a sound.

Thinking it could be the audio card i used the onboard card but nothing changed.

i also installed uni xonar driver on low DPC setting but nothing changed. I really don't know what to do if not go back to windows 7.

here's the last log on latencyMon :

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.

i also asked on uni xonar driver website since i see cmudaxp.sys is high but they kindly said that this mean nothing. It could be another thing that puts its DPC high.
By the way, latencyMon says windows 8 but it's windows 10, i don't know why.

I really hope you could help me.

Thank you in advance :)

Hi Calcifer ... and welcome to the forums

Have you had any luck with the stuttering yet?

I wish I had more experience with gaming systems, but most of my customers are businesses - so my tips will be limited to information mainly from research and reports.

1) I'll assume when you disabled HPET, you did so in both Windows and in the Bios: if not, try that.
2) A quick way to rule out the Intel lan driver is to disable your Intel lan in Device Manager (if your networking is usually wireless, won't hurt anything... If your networking is usually wired, then see if you have an extra non-Intel lan card to test with [with the Intel lan disabled])
3) To rule out any malware interference, run a few scans.
4) Turn Latency Monitor off when gaming: it does add a bit of overhead.
5) Check on your Startup programs with Task Manager (it has a separate tab in Windows 10)
6) Set the Windows 10 feedback to "Basic" (if it is either "Full" or "Enhanced") Settings > Privacy > Feedback & Diagnostics > Feedback frequency = Never (during your testing) ... Diagnostic & usage data = Basic.
7) Limit unnecessary access to your network for sharing during gameplay ... Settings > Update & Security > Windows Update > Advanced Options > Choose how updates are delivered > Updates from more than one place = OFF
8) Make sure the game cache in Steam is OK = In Steam, right-click over Arma 3 and select "Properties". There go to the tag "Local Files" and select the option "Verify integrity of game cache..."

.. Oh, and the reason Latency Monitor shows Windows 8 rather than 10 is that it hasn't been updated to work with Windows 10 yet (so the reports might not be quite as accurate as in Windows 8). Windows 10 does have its own performance monitor, but I haven't used it much yet.... I've heard that it can provide a reasonably readable report, complete with a bit of troubleshooting notes: type perfmon /report into your search box and press Enter. (Make sure there’s a space between “perfmon” and the slash mark)

Let us know if a cure proves elusive.

One more thing:

You could also have a look in your nVidia settings for "sync" options: there's a utility called V-sync, N-Sync, or G-sync ... (I'll be danged if I can keep them straight ... bunch of different versions) that helps stuttering in video/audio by adjusting frame rates and such - to work best with your monitor/audio setup.

Hello OldGrayGary

fist of all thank you very much for answering.

i'll answer your point with the quote

2) A quick way to rule out the Intel lan driver is to disable your Intel lan in Device Manager (if your networking is usually wireless, won't hurt anything... If your networking is usually wired, then see if you have an extra non-Intel lan card to test with [with the Intel lan disabled]) unfortunatelty i only have 1 lan card ( the integrated one ) and i don't have wifi even in my house :) i kinda don't like it. i also bought a usb adapter to bypass the lan card but the stutter was still there.
3) To rule out any malware interference, run a few scans. done
4) Turn Latency Monitor off when gaming: it does add a bit of overhead. thank you, i didn't know that
5) Check on your Startup programs with Task Manager (it has a separate tab in Windows 10) done, honestly i don't know what should i see that shouldn't be there.
6) Set the Windows 10 feedback to "Basic" (if it is either "Full" or "Enhanced") Settings > Privacy > Feedback & Diagnostics > Feedback frequency = Never (during your testing) ... Diagnostic & usage data = Basic. it's already basic
7) Limit unnecessary access to your network for sharing during gameplay ... Settings > Update & Security > Windows Update > Advanced Options > Choose how updates are delivered > Updates from more than one place = OFF already off
8) Make sure the game cache in Steam is OK = In Steam, right-click over Arma 3 and select "Properties". There go to the tag "Local Files" and select the option "Verify integrity of game cache..." i'll do this but i just opened arma 3 because it was faster to see the error in latencyMon. to be honest the micro stutter issue doesn't affect much this kind of games but only moba or similiars ( like diablo 3 ) , i really don't know why.

.. Oh, and the reason Latency Monitor shows Windows 8 rather than 10 is that it hasn't been updated to work with Windows 10 yet (so the reports might not be quite as accurate as in Windows 8).

(Make sure there’s a space between “perfmon” and the slash mark) ok, thank you , i didn't know there was a report tool in w10. i did it and it says it's all ok. i tryied to save it so you could check it but it's really long. i think the only way is to upload the file. tell me if you want it :)

this is under testing and i thank you, i didn't know that. actually i've seen it before but i never thought it could cause micro stutter issue. now i'm trying adaptive sync but i still see micro stuttering issue( maybe less ! it could be a good point ). i still have to try adaptive with halfed fps ( though i go to 30... ) . G-sync is something i can't have since in order to have it you need a monitor that support it.

if you know what else can cause it i'm all ears :)

thank you again .

Hope it gets better with a little tweaking. I'll stay tuned ... and I'll post any other tips I come across that might help ....

Hi, i kept trying different things. manage nvidia control panel, turning off dolby surround from audio panel ( this seems to have lowered dpc though i think it's normal since there are less things to do, i suppose ).

here the new log and as you can see unfortunately nothing changed ( in the meanwhile i updated gpu driver since newer has come out ) :

i did also some screenshots :

i also did a xperf file and it says the same thing i suppose :

i really don't know what else to do...

thank you again for your attention.

The C-media driver and the Intel ndis driver are impressively awful in your graphs.

What USB devices are you using currently? (mice, keyboards, capture devices, external hard drives...) The Wdf01000.sys driver shows a lot of latency, and it is often used by input/output devices like USB devices. Especially wondering if you have a USB headset or something like that ... it might have a drive we can try working with.

If you'd like, you can try the SysNative info-gathering app - and post it's logs here. It will allow us to look at the pattern of errors & details about the drivers. Here's a link to the post for it here at SysNative (it has instructions ... for now, mostly use the info app ... and perhaps try a few diagnostics, just to make sure the hardware isn't part of the problem) ....
https://www.sysnative.com/forums/bs...windows-10-8-1-8-7-vista-post303.html#post303

Might try the Performance Monitor's "health report" idea too --- since it is built into Windows 10, we know that it's completely compatible with Windows 10 (whereas Latency Monitor hasn't been updated since Windows 7, and it's results might not be completely accurate) ... save the PerfMon report as html if you can. Note that on some systems, the health report hangs & never finishes (a few of our forum visitors have PCs with this symptom, and I've seen it myself on an older Toshiba laptop ... I haven't yet solved that particular puzzle ...)

I'll try to find a clue that helps from the info files.

hi, thank you so much for answering me. very kind.

i have plugged in USB PORTS, mice ( logitech g600, i have installed logitech gaming software which is the software that you take when you try to download the driver. So i suppose it's with it ), keyboard ( CM trigger-z , even though the keyboard worked without driver, i've installed its own software that provide macros option on keyboard ) , xbox360 controller and Wacom intuos ( installed both windows driver , automatically after plugged in , and through cd which install a software that keep it updated. i also noticed on control panel in the software list installed " WebTabled FB Plugin 32" and also 64 bit. I think windows installed it automatically . all these things are in usb port 3.0 except mouse and keyboard that are in 2.0 ports. this because asrock h97 pro 4 got only 2 usb ports 2.0 . thouhgh i don't think it's a problem. Headphone ( superlux hd 681 evo ) and microphone ( a standard zalman ) are plugged in directly to the asus xonar dgx.

I've tried to use the SysNative info-gathering app but a txt appears saying this :

There is a problem with the Environement variables on this system.
Unable to determine the location of the Documents or Desktop folders.

i guess it's because i did another user folder on D ( the hdd ) to avoid to write on C ( the ssd ) where i have installed only the OS.

for the performance monitor i've tried for kinda two ( yes... almost 2... ) hours to do a damn ( sorry ^^ ) report without results.... i've read on different website how to do it but... i don't know.. i'm messing up something. i'm sorry.

The PerfMon /report command problem (where it just runs and runs and runs ... but doesn't finish - is not your fault. I experienced the same effect on a Windows 10 Toshiba laptop here in my work area: I still haven't been able to isolate why the issue only affects certain computers. So far, I haven't seen any sort of fix for it yet -- which is too bad, since it's a nice tool (and reasonably quick, when it works).

Since you have so many USB devices, you might see some relief if you unplug a few when they aren't in use? (Maybe not a huge chance of success there, but can't hurt to try..... especially when gaming.....)

Since there is a mention of some heavy use of the page file, if you haven't already set your Virtual Memory settings manually, you could give that a try. A little extra room might help Windows to not get carried away with swapping stuff on and off the page file .... Since you have 8 GB of system memory, you could try things with a minimum setting of 8192 MB and a maximum setting of 16384 MB .... I realize the upper setting is a bit generous, but I figure it's worth a try. You can also experiment with seeing what works best for the page file ... (depending on how crowded the SSD is) ... you could try the page file on the SSD if there's enough space ...

I imagine you've looked for the latest Windows 10 drivers for the Asus sound card (and, heck, most of the USB devices, too) ... if any of them are a bit old, keep hunting for newer drivers & hope for a nice catch.

Perhaps and easier way to test out limiting resource usage would be to simply use Device Manager to temporarily disable some of the USB devices not being used --- that might be better than unplugging the devices (since toggling them from Enabled to Disabled will also temporarily turn off their associated drivers)....

I haven't yet heard if the Intel network driver (ndis) situation has improved yet.... I would expect something causing as much slowdowns as it has been associated with will get decent priority for improvement from Intel....

If the Windows 7 drivers allowed you to have the same equipment all running at the same time with no lagging or popping in the audio, it's not the worse thing in the world to go back to Windows 7. It all depends on how the troubleshooting goes . . .

Let's see if something improves soon.

for asus xonar dgx i've installed unofficial drivers , uni xonar , that provides a LOW DPC installation option. i'll try what you said.

abou the SysNative info-gathering app, how do i solve the problem since it doesn't starts ?

thakn you again.

UPDATE !

ok I MIGHT found the problem. i think it's the high definition audio device of the gtx 970 that created conflicts, though i installed only video drivers through installation and i left unchecked the hd audio drivers. i tried different times to uninstall and disable it from the device manager but after the OS restart it's still there. if you know how permanently disable it , would be cool. i toggled off in control panel the option that the system auomatically install it but nothing changed.

Hi again

Tell you what, try
1) Download the most recent non-beta nVidia drivers for your card.
2) Completely uninstall the current nVidia drivers (especially the audio drivers!)
3) When installing the newest nVidia drivers from your download, make sure to choose Custom (Advanced) for the type of install (this will force the installer to include only the components that you select). Try using the checkboxes to install only the graphics driver and GeForce Experience, and uncheck the boxes for the 3D Vision Controller, 3D Vision Driver, HD Audio Driver, and the PhsyX System Software.
4) Also make sure to check the box for Perform a clean installation

Here's a screenshot example:

See if that helps at all ....

it's what i alwais do. but tnx anyway. the point is that windows 10 automatically install and activate it.

OldGrayGary · Apr 2, 2016

See if you can disable it in Device Manager. I would expect it to show up in there if it is installed --- Windows should leave it alone if it is manually disabled in Device Manager.

OldGrayGary · Apr 2, 2016

P.S. .... it will still "show" in Device Manager, but it should show as Disabled. It shouldn't get "re-activated" or "re-enabled" unless you manually do that yourself.

Calcifer · Apr 2, 2016

yes, i disable it first and then uninstall it and it dissapears from the device manager menu. the problem is that if i restart the computer it comes back.

OldGrayGary · Apr 3, 2016

Oh, sorry, I should have mentioned this before: once you've disabled the nVidia audio in Device Manager, that's all you have to do. Don't uninstall it - just leave it installed but disabled. Having it installed keeps Windows from automatically re-installing it again (which makes the loop of craziness start again) ...

Our goal:
We want the nvidia audio installed - but disabled.

Calcifer · Apr 3, 2016

ok this seems to work, thank a lot for these tips. i'll test out and see what happens.
for now i've uninstalled logitech ( for mouse ) and Cooler master software ( for keyboard ) drivers since i can use them without. i also diabled the xbox controller and the wacom tablet but nothing changed so i renabled them. i'll let you know if with nvidia hd audio disabled it's better or even fixed.

btw whan can you say about c-states on UEFI configuration ?

thank you again for you help, patience and kindness.

Calcifer · Apr 3, 2016

ok update, i had it again. here the updated latency mon report :

i don't know what else to do. i even disabled lan card through UEFI and used an ethernet lan adapter.

OldGrayGary · Apr 3, 2016

Hi again

I'm not sure how accurate the Latency Monitor results are, since the program hasn't been updated since Windows 7. You can try creating a cpu trace with Windows 10's Performance Monitor ... hopefully that would work (though since it had trouble creating the health report, it's not certain).

Did we check your Virtual Memory settings yet? If it is currently set to have Windows 10 automatically adjust things, try setting the range manually, and see if there's any effect. Since you have 8 GB of system memory, a reasonable range would be 8192 MB for the lower setting and 16384 for the higher setting.

See if you can get the SysNative info collector to run - you can try it with administrative rights, and if that doesn't help, in Safe Mode (also with administrative rights).

Make sure that Latency Monitor isn't running when you are testing for the audio/visual effects: Latency Monitor itself can show rather high latency.

And ... one of the things you still have the option of trying: make a system image backup, and then go back to Windows 7. If everything runs well in Windows 7, it just might be that the Windows 7 drivers work better for your hardware/software mix. You could still upgrade your Windows 7 to Windows 10 again until July 29th of this year. You could make a system image of your Windows 7 then, too, if it is working well -- in case Windows 10 just doesn't behave itself either now or on a future upgrade try.

I've had to move some of my customers computers back to Windows 7 - but most of those were at least six or seven years old, and were borderline compatible for Windows 10. Windows 7 will still continue to get security updates until mid-January of 2020.

Let us know how things go. If you want to keep working on getting Windows 10 to a non-stuttering state, our next step is to get the info-collection app to run. There might be a clue in there.... and try a Performance Monitor cpu trace.

Hope for the best!
