Windows 8.1 High DPC Latency,(annoying static sound)-Help.

Q: Windows 8.1 High DPC Latency,(annoying static sound)-Help.

Hello everybody.
Before I start I just wanted to say , sorry for the bad english .
So , I have read allot of forums lately , and I found out that windows 8 and windows 8.1 weakness is its latency.
For me this proplem accoured like 2 months ago (before it didn't happend) , and yes I have messed around with the bios before that happend (now its all set to default )
Currently I am running Windows 8.1 Update 1 (made a clean install yesterday) latest updates and drivers installed (with a program called DriverEasy) , and I am also running all the default settings in bios currently . I noticed the problem , 2 months ago just like I said before , when I was watching a video on youtube . Since that , I just can't watch some videos anymore with the ANNOYING static/crackling sound , its very annoying .And it also seems that it affects CPU performance and fps drops.Like I said before , I installed Windows 8.1 yesterday , so no minor tweaks have been done to the system .

I have already tried :

-"disabledynamictick" command
-Disabling all unused devices in bios
-Disabling EIST and C1E (no improvment at all)
*-Disabling HPET Mode reduces latency , but pc isn't stable.

Here are my computer specs (its a 4 year old and its really , really bad ):

Gigabyte G41MT-S2PT(motherboard)
-Intel Celeron E3400(processor)
-Intel G41 Express Chipset(intergrated graphics card - really bad)
-4Gb 1333Mhz Kingston DDR3 Memory(ram)
-Windows 8.1 Update 1 (latest drivers and updates installed)

Here are the screenshots of DPC Latency Checker and Latencymon :

DPC Latency Checker (2minutes):
There are one or two yellow once a while .The values also slightly raise to yellows when I move the mouse , which I think is normal .

Latencymon (2minutes-both pitcures):

The values were
raising and falling

The values were
raising until I stopped
the checking .

My power plan is set at High Performance (when the powerplan was set to Basic , I was getting red spikes in DPC Latency Checker) , and I am running the stock voltage in bios for the cpu 1.28750V.

I realize this might be a hardware related problem , but I am little bit more sure that this is a Windows 8.1 problem hopefully they will fix it in the Update 2 .

Help would really be appreciated.

Every reply would be helpfull...


P.S.Sorry for the bad english.

EDIT:Today I noticed that the sound popped , when I started my computer at the windows logo.

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

A: Windows 8.1 High DPC Latency,(annoying static sound)-Help.

Windows 8 Compatibility:[FONT=Arial] The DPC latency utility runs on Windows 8 but does not show correct values. The output suggests that the Windows 8 kernel performs badly and introduces a constant latency of one millisecond, which is not the case in practice. DPCs in the Windows 8 kernel behave identical to Windows 7. The utility produces incorrect results because the implementation of kernel timers has changed in Windows 8, which causes a side effect with the measuring algorithm used by the utility. Thesycon is working on a new version of the DPC latency utility and will make it available on this site as soon as it is finished.

Beside that it's most likely a hardware / driver / codec - issue.

Your system is also not really powerful as well.

Windows 8 / 8.1 are not causing that kind of issues. There is only an input-lag, which can be fixed via M$-tool, when playing older games without direct-/raw-mouse-input.

I recently installed the 64 bit version of windows 7 ultimate on my computer and it was a fresh install, i had to fresh install because i had 32 bit windows 7 but i wanted 64 bit because of its capabilities with my games so i installed ive started hearing these like glitch sounds when listening to music and doing something else (Playing games, surfing the web) so i looked on forums and what i got was a download to get this DPC latency checker so i did that and i noticed when the music glitched the bar shot up the program and a few people on youtube said to go to device manager and disable/re-enable some devices, i did that and it wasnt working... i have a hunch that it may be the graphics driver i installed for playing minecraft

At first everything seemed fine. Everything was working, I only needed to upgrade the VGA driver.
I have a xonar D1 card with uni-xonar which worked immediately.

Than when I listened to music I noticed clicking and stuttering which got really horrible after while.

Talked about it on hydrogenaudio: Clicking, stuttering after upgrade to Windows 10 - Hydrogenaudio Forums

I clean installed VGA, updated the LAN driver, re-installed xonar. Things improved but they still suck. Clicking is still a regular occurance.

I checked latency when LAN and the soundcard was disabled but latency still sucked:

Since I was using the very same hardware for years without these issues and I have doubts that several hardware or their drivers suddenly started misbehaving I'm guessing it might be an issue in win10 itself.

I attached the latest measurements. (screenshots and report) The worst values still belong to the same as the first time: VGA, soundcard, LAN, USB, ntoskernel

Don't know what else to do.

A:Clicking, stuttering sound after upgrade to Windows 10 - High latency

The latency-problem is usually caused by the latest Intel network driver. There are countless threads about this and easily google-able. There is no real help, Intel is promising to "look into it" for over a year now and still no fix.
I changed to Realtek NIC because of that - best €10 I ever bought for the computer, to have no problems.

My specs: Dell Optiplex 745, Quad core Xeon X3220 2.4ghz, windows 7 64bit, sound max driver, PNY GTX 550 TI. Fresh install btw, win 7 sp1, i haven't install any chipest drivers because i don't seem to need them , even though i did before and it didn't fix the problem when i was using a e6600.  and i don't have the installer disc for the dell 745.
The latency issues, sound crackling noise only happens when i install drivers on my GPU and i have tried pretty much every driver. Here's the strange part, it seems to be affecting certain games, but not ever game. And the sound issues are really strong, even when im sitting at the desktop listening to music, if i hit refresh i can hear the static and crackling noise. I ran the test without installing the drivers, all green mostly, soon as i install the drivers so my gpu will work, its red and green and high latency .
I figure its my mb , but im trying to figure out why when gaming it only affects certain games, while others work perfectly fine. could a faulty mb be the cause? because i have no idea how to solved it. and i won't have the money to buy a new mb until next month. its only affecting about 4 games, and i can't play flash browser games, oto much static bad performance.
oh and despite this, videos on *** or youtube 1080p runs flawless, no sound issues. strange right?

After having my motherboard, graphics card and RAM replaced due to a power surge, I have been experiencing high audio latency, along with very poor sound quality which includes static noise, crackling. The sound is similar to that of an untuned radio.
The sound quality is decent when I am running limited audio programs, but when I run multiple (Such as Skype + Youtube), the sound quality starts to become poor.
The sound quality also becomes poor quite frequently when I am only running one audio program.\

I've already tried going into Device manager and disabling/reenabling drivers to see if they were the cause of the problem.
I've also tried updating the drivers to the latest version.

Not really sure what to do now, help is appreciated gratefully.

A:Audio issues (Static + crackling) and high audio latency

FWIW, the DPC Latency Checker is not fully Win 8 compatible (there is notice on their web site) and it can give you false latency hits.

Hey there,
I've been having an issue for a few weeks with very high DPC latency coming primarily from USBPORT.sys (which I understand is the LatencyMon software). There are also a smaller number of DPCs coming from other drivers which you can see in the .etl.
I've tried everything I can think of: updated chipset drivers, updated usb drivers, updated graphics drivers, tried all of the fixes listed on Google when searching for "USBPORT.sys dpc latency", etc.
It should be noted that the latency is very inconsistent. Some days there is still high latency on DPC latency checker but not audibly so and other days the audioi is mostly silence with the occasional stutter of audio getting through.
Can anyone have a look at the .etl file and see if they can figure out how I can fix this?

It should be noted that I get the latency with or without the audio interface or graphics card.

Hi and Welcome to TSF

Sounds as if your having some type of interference, sometimes speakers sitting too close or a cell phone sitting nearby will cause this.
What kind of a mouse are you using, try a different one to see if it still happens.

I've had a lot of issues with my motherboard (asus maximus viii hero) but the most annoying one appears to be related to intel's ethernet adapter I219V.

Basically whenever i download something or use the internet for a long time i would get huge sound stuttering issues. They appear ONLY while internet connection is active and only while something is downloading (while watching and caching youtube videos for example).

The issue gets progressively worse the longer the internet is active as well and after a few hours and heavy usage i get 14ms delays on ndis.sys and sometimes tcpip.sys too.

I've tried contacting Asus support four times to no avail - they confirmed that this is an issue related to intel's adapter and windows 10 and recommended me to buy additional cheap lan card (what's the point of having a gaming motherboard i wonder?), i've also tried writing in intel's forums which contain at least 14 pages of complaints related to this issue but apart from some shady guy claiming to be an engineer we didn't get any response and the only thing he recommended was to contact the manufacturer.

I've also set my CPU performance to 100% and disabled speedstep in BIOS which didn't help at all. I also keep my bios and drivers relevant but it doesn't make any difference. While running sfc /scannow i had not encountered any issues either.

Another solution seems to be to install much older drivers which do not produce this issue but unfortunately it doesn't work for me since th... Read more

I have ASUS X540LA Windows 10 64 bit Version 1511 (OS Build 10586.104).

I am getting a static sound even when muted. The sound isn't coming through my earphones but is still heard from the pc even with the earphones plugged in.

I hear what I expect to hear, and nothing more nothing less, through my earphones.

I have disabled and uninstalled my RealTek HD Audio Device and Driver but I believe this is only silencing the issue and not resolving the problem.

Disabling and uninstalling the audio device and driver has rendered sound completely unavailable.

I would like to resolve the problem without opening my pc and cutting specific speaker wires.

What is going on with my lappy and how can I resolve the issue?

Hello every one, since installing windows 7 professional i have been getting random spikes every now and then, when streaming from the internet like youtube, and its driving me insane. I've tried lots of things to try and solve the problem... But to no prevail! I will list below.

1. Turn off intell speed thing in bios (stops the cpu from going to sleep)
2. Turn off "allow the computer to put this device to sleep" on power management for lan card.
3. Turn off on board lan and use a seperate dedicated lan card (the card is not expensive only a 7 pound stlab n-210) and turn off let pc turn it off blah blah
4.disable HD5770 HD sound (in device manager i disabled it, but i dont think thats the problem)
5. Stop using morzilla firefox and tried using microsoft explorer (a latency monitor program advised me a extension in firefox was causing the spike)
6. Turn off onboard sound and use USB sound instead (i have both usb speakers and usb headphones)
7. Reinstall windows 7 pro and get all updates.
8. Uninstall mcafee and try browsing without it
9. Praying
10. Shouting at the computer.
11. updating every drive on computer, lan cards, graphics, windows update and so forth.
12. Updating bios (flash update) 1.7 latest for my mobo
13. read lots and lots of threads on many differnt leads to the cause, but finally i'm in belief its the lan, since unplugging the internet stop all the spikes and replugging it in causes instant spikes.

And still i can not solve this problem, its dr... Read more

I was wondering if anyone found a solution for a high latency issue with intel's ethernet drivers and windows 10 which results in ndis.sys driver producing stuttering? It's a known issue which became worse with the release of windows 10 and apparently the only solution so far is to use older drivers which only work on windows 7 and 8.

Basically whenever i download something big and or use the internet connection for several hours the ethernet adapter starts producing latency spikes. I've contacted motherboard support 4 times and been told that this is an intel's issue or that i should buy additional cheap lan card or just wait for a fix but and im kinda tired of waiting. Also intel never properly responded or confirmed this issue either, apart some guy claiming to be an "engineer" and writing a couple of messages on intel's forums basically saying "this is not our issue go and talk to motherboard's manufacturer".

I recenly purchased a 2017 Spectre 15 x360 (512/16/i7). Loving it so far except when using any 2 finger gestures on the trackpad. I noticed that whenever I scroll pages using 2 fingers or performing any 2+ finger gesures (like zooming or swiping up with 3 fingers to get task view), there is an annoying static/buzzing sound coming from the speakers. It just happens when 2+ fingers register on the trackpad. When I point around using 1 finger, the static isn't there. The sound does not get louder when I crank up the volume.  This is surprising since HP touts that special care has been involved in designing the audio components such as extra shielding and stuch. But it doesn't seem to be the case...    I recently updated the audio driver but rolled it back because it didn't fix a problem. But I didn't really notice any static before updating the driver. However, I'm not sure if this is the cause since I wasn't in a quiet enough place to notice.  It's not that big of a deal but in quiet environments, it is very noticable.

Not sure if I'm posting this in the right subforum - I've been having crackling/popping audio issues while playing games and using audio programs, and I've been trying to isolate the source/fix the problem, to no avail.

I ran LatencyMon for almost an entire day without really touching the computer or running any programs. Here are the results. Run on a Lenovo Thinkpad T530i.

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.

I have a question about ping times, latency, and jitter.

I believe I understand the concept of jitter. If I ping www.google.com, and get some results of 10ms and others of 100ms, my jitter is 90ms; right?

If that's true, here's the question I have:

Is it ever preferable to have a connection with higher latency but less jitter? For instance, would it ever be better to have a 100ms latency with zero jitter than it would be to have latency that fluctuates from 10ms to 100ms?

One possible application I could think of would be something like VoIP or videoconferencing, where (perhaps) you would prefer consistency, even if it means higher overall ping times.

I hear a really high pitched sound coming from my computer, specifically my PSU.
I can only hear it from certain angles, but it is really annoying after a long time of putting up with it. How do i diagnose where the sound is coming from and if it's the capacitor or the fan?

The sound goes away when the PC is off.

Any help would be appreciated.

A:Annoying high pitched sound coming from my pc?

This sort of high pitched noise is usually a vibrating coil. Unfortunately coils (aka inductors) are common components on motherboards, graphics cards and PSUs.

Are you 100% sure it's coming from the PSU ? If so there's not much you can do except try to ignore it or get another PSU.

It could also be a worn fan bearing. Try to locate it exactly.

Also, I'll be browsing without any problems, everything running smooth and all of a sudden I lag out and a page I may be trying to load will continue attempting to load with no success until I exit my browser and restart, than it will go back to normal browsing speeds until the next spike...

Hello everyone this is my first post here.

Well where to start, I was looking all over the internet to fix my Very high latency
as you can see it was very high all the time and it was really annoying when listing to music,playing game,watching videos ect.

I tried everything from disabledynamictick = Yes to unplugging my GPU and HDD even re installing windows.

Then i thought i wonder if windows wants to be dumb and put power settings to "Balanced" and it did so i changed it to "high performance" and VOLLAAA!! DPC went way down and there is no more crackling or stutter

Hello all - hoping some real experts can shine a light on this one.

Installed a brand new mobo - Asus Sabertooth 990FX - and DPC latency checker was showing full red. Used Latency Mon to track down the culprit which was storport.sys. Searched everywhere for a driver update for storport in Win 7 and nothing exists.

Then went further and installed Windows Performance Toolkit and ran the Performance Analyzer to look at what was going on with storport. PA showed that the "RaidAdapterTimerDpcRoutine" was causing storport to spike so badly.

I'm not running any RAID drives - they're all set to AHCI in the BIOS, so I'm at a loss what to do next. All latest drivers & updates are installed. Are there RAID related drivers I can disable from device manager? Or switches in the registry?

A:Very high DPC latency in Windows 7 x64 caused by storport.sys

Well I seem to have finally fixed my endless DPC problems. I performed a fresh install of Windows 7 and carefully installed all drivers and updates for everything in the following order:

- Asus motherboard drivers
- Flashed the BIOS and reinstalled latest vers.
- AMD CPU drivers
- All Windows 7 important updates incl SP1
- GPU drivers
- and lastly, the drivers for the external firewire audio device.

Hardware wise, I changed the slot that the GPU was installed on. I had it in PCI slot 3, and on reading the manual, they recommended slot 1 for the GPU. I also removed an Astrotek PCI firewire adapter card which was not being used. The new mobo has an external firewire slot that I've plugged into instead.

I also kept the driver installs "lean". Only installing the essentials. So I did not install the AI utilities for the Asus mobo, as I saw the AiCharger.sys misbehaving at one point. I also only installed the graphics drivers for the GPU - not PhysX, or 3D etc etc.

Something in that mix of changes was the secret sauce to fixing the DPC problems. Now I can run video, audio, flick between screens rapidly at any resolution and DPC never peaks above about 153. I've even still got aero running. I've got fingers and toes crossed that this remains stable, but this is the first time I've ever had Win 7 so calm since first installing it 18 months ago. I was never able to install and run my audio production software through Windows 7 due to these issues and had a dual boot mac... Read more

I just recently installed windows 7 x64 professional edition. Love it! Minus one thing. My wireless network adapter is crapping out from it. It appears Windows 7 doesn't like any other previous wireless network adapters that much. I am only getting 36Mb/s and I have HUGE latency when playing games online. I am running Linksys WMP300n. I just bought this thing last year when I got Visa. It worked amazing for Vista, but as as soon as I install 7 it hates me. I looked at the drivers and It wont even recognize a Linksys. The ones listed in the device manager are just generic drivers vista provides the Broadcom 802.11n drivers.

Anybody know of an adapter that works with 7 and or a remedy to this. It seems with the small amount of research I have done so far. LOTS of people are having troubles with wireless network adapters for windows 7.

I recently formatted my hard drive and did a clean install of windows 7.

Lately ive noticed that while watching youtube videos or listening to music in windows media player, ill get these random stutter moments where the computer just seems to slow down for a second. It makes my audio/ video/ and mouse all stutter.

I ran DPC Latency checker and found that at the moments I had stutters, the latency checker was spiking up to max in the red.

I read around online that it is the network card that causes this, so i disabled my network card and the latency checker remained in the green.
Then I tried reconnecting my internet via wifi while the network card was disabled, and once again I started getting spikes.
I also tried updating my network card to the latest driver and now its even worse....

can someone please help me? These random stutters are starting to get annoying.

Also a side note:
Ive noticed that if the driver is enabled, and im not doing anything network related its all fine. But once I do something like load a page or load a video, thats when I start to get the random stutters.

Update: I ran latencymon and I found that flash player is causing many hardpage faults, and that a driver called ndis.sys - NDIS 6.20 driver is causing my latency spikes.
Here is the summary report

Hi Lenovo and everyone, I have two issues with the sound of my Y700-15ISK:I.When any Realtek driver is installed that includes support for the subwoofer, a high pass filter is applied on the main stereo speakers, making sound poorer and more mono-like, especially with enhanced bass using an equalizer.(High pass filter removes low bass frequencies from the main stereo speakers.)(When the default Microsoft driver is installed that does not have subwoofer support, no high pass filter is applied on the main stereo speakers.)Is there a way to disable the high pass filter? I would like bass to come from the main stereo speakers as well. I see no such option on any of the available GUIs, is there such an option from a Command Line Interface?If there is no such option currently, could you put this option in a subsequent driver release, or simply remove the high pass filter from the driver?If you do not have the resources to do so, could you enable us to modify the driver source code and create a custom driver without high pass filter? I am sure the community would love the enhanced music coming from this and similar laptops using the updated driver.(Win 10 or Win7) II.Only on Win7:Subwoofer is out of sync with the main stereo speakers resulting in echo.Happens using Lenovo's Win7 64-bit, Win10 64-bit, and Realtek's generic driver as well. Could you guys fix this? Does anyone have a solution for these? Thanks,Andras

Hi guys,
Yesterday evening I was watching some youtube videos when suddenly the sound cut out. I turned the volume back up only to find there was a loud staticky crackling pop as the only audio output. Audio output is fine on headphones.

I have a Lenovo Yoga 920 (with highest specs) with Windows 10 home 64x bit. Since the issue arose, I have tried several things:
- disable/enable drivers by REALTEK related to sound, and Qualcomm Wifi Network Adapter

-Reinstall drivers via windows and directly via REALTEK website
- Update Windows 10 OS as well as BIOS
- Messed around with several battery plan settings
- Restored PC to previous backup, then messed around with audio mixer. This helped, as there was no distortion until volume 20, but beyond that it was the exact same issue.
- Lastly, I resorted to just resetting my computer (deleting all files, etc.)
My next step would be to do a clean install of windows 10 but I need to be using my computer and was wondering if there is a better way.

I believe this is a software/driver related issue as I was partially able to fix it by messing with the mixer settings (even when not having restored my PC). However, this "fix" doesn't work since I reset my PC...
I installed LatencyMon, and the results are below:

Okay so I upgraded from a crappy desktop computer with XP to a new ASUS laptop with windows 7 for the purpose of more portable audio recording, yet every time I try to record more than 1 track of audio, I have serious sound delay/latency. I have attempted troubleshooting the issue for months and months, with no solutions whatsoever. I have done absolutely everything in my power to fix this issue, messed around with all my audio settings, updated and rolled back drivers and I seriously have no idea how to fix it. I threw out my old computer so now this my only option. my friend also has a desktop computer with windows 7 and I tested the audio recording and found it had the same issues as mine.

I need help urgently, I invested 900 dollars in a new computer for recording and it's a total lemon thanks to windows 7. Please, help me.

any light shed upon this topic would be greatly appreciated

A:windows 7 sound latency

and for the record I have tried many different audio recording software to ensure the problem was only with my computer and not the program. My old recording setup was a USB guitar pedal and ACID PRO 7.0 which I never had any problems with. Suddenly this same setup caused serious latency in multi track recording with my new computer.
I have also tried with my computer microphone and the problem persists. I have googled this problem endlessly, tried various tweaks and settings and audio software and have barely noticed an improvement. my various audio recording programs do have a way of adjusting latency but I have no idea what setting they should be at, and experimenting with these settings have only caused me headache after headache.

basically if I record a rhythm track with my guitar, if I record a second track on top of it it's always out of sync with the first track. I have read on google countless people using windows 7 with the same problem and nobody seems to have a solution. believe me, I am not a beginner to using computers. usually with trial and error I can solve most basic computer related problems, but this honestly has me stumped. I'm seriously at the point where I'm considering buying a crappy windows xp computer just so I can record music again

windows 7 is supposedly an upgrade to XP, yet XP was about a thousand times easier to use for recording music. I would do anything just to have my old recording setup back.

Since Jan-Feb of this year I have encountered the following issue while trying to play games on my laptop.

Abnormally High CPU Usage
Extremely low FPS - After 5-20 Mins of play.
Extremely High latency to servers - from 300 - 900 after 5 - 20 mins of play.

The thing is all of these started 1 year after I been using this laptop, after a full year of everything running flawlessly all these issues kicked in after I performed a clean install in Jan., I even performed one in Feb. and one 3 weeks ago, since someone suggested this could fix my issue and I still face the same problem.

I would kindly take any suggestions since I am so desperate that I am considering trowing this device out the window.

Here are my specs:

OS Name Microsoft Windows 7 Home Premium
Version 6.1.7600 Build 7600
System Manufacturer Dell Inc.
System Model Studio 1558
Processor Intel(R) Core(TM) i5 CPU M 520 @ 2.40GHz, 2400 Mhz, 2 Core(s), 4 Logical Processor(s)
Installed Physical Memory (RAM) 4.00 GB
Name ATI Mobility Radeon HD 5400 Series
Adapter Description ATI Mobility Radeon HD 5400 Series
Adapter RAM 1.00 GB (1,073,741,824 bytes)

A:High CPU usage, low fps, high latency.

All of your symptoms could be a driver issue. Please download this free latency checker and run it to see if it is.

For all of you experiencing a sound lag while trying tomonitor a live recording in Windows 8, all this talk of updating drivers andtweaking what not is pure B.S. I havedone extensive research on this issue that first reared its ugly head with the onsetof window 7 (the problem did not exist in XP or Vista) at that time thousandsof musicians actually signed a petition that was sent to Microsoft asking themto deal with this issue? THERE IS STILL NO FIX!!! The problem is in the OSitself and the way it processes an analog signal into digital? After severalexcruciating mind numbing calls to the upper reaches of the Ganges River where customer serviceis apparently located (and no one there knew what the hell I was talking aboutanyway)? I finally reached a tech that was actually located in the good old USAand he confirmed my suspicions that there is absolutely nothing that can bedone until Microsoft issues an upgrade to the OS itself? until that day comes (ifever) you will not be able to monitor a live recording in real time withoutbeing subjected to a significant time lag? Your only choice is go retro with Vista or XP or dump Microsoft all together and go with a Mac...

A:Windows 8 sound latency monotoring live recording

I have a recording studio. We "fight" latency issues regularly. The latency issues have been there since before Windows XP, its not something that started with any particular OS.

BTW, Vista handles audio functions the same as Win 7. XP handled some audio functions differently but nothing that affected (recording studio) latency.

I've had broadband for a few months from central-point, 512mg. I used to get speeds of about 70kbs download and latencies of about 40-60 on Counter-Strike Source. Now, I get downloads of about 50-60kbs (not too bothered about that) but latencies of about 300-500 on CS:S! Anybody have any ideas? I did have some problems with my router, and I restarted it, but I'm not sure if that was before or after the low latency.

I've emailed central-point, but I fear it's a scam to get me to buy 1mg.

(See also the attached screenshot - the timeout always happens on the first hop.)

A:High latency in wow

Seems like a problem with your internet provider. Ring them up (or email if you prefer) and ask them if they can turn off interleaving as you are having ping/latency issues. That's what my ISP did and my ping on counter strike went from 100ms+ to 10-20ms.

There may be an option in your router to turn it off but contacting your ISP is the best bet.

Hi guys,

Ive spent last 4hrs trying to fix the high DPC latency I have and have been unsuccessful.

Ive ran combofix and I kept getting BSOD, so I had to run it in safe mode.


Thats what it deleted but it hasnt solved my problems and I really do not want to format. Ive tried disabling so many drivers in device manger and nothing has worked for me.

Here are two screenshots from dpc latency programs.

Welcome to TSF.

I'm not sure why you decided to use Combofix on what looks like a likely graphics driver/hardware issue.

I'm getting a lot of high latency for some reason. I tried everything I found on google, and nothing worked. I disabled processes, but still. When I get those latency spikes my mouse and everything else lags for a while. What is causing this?

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.

I ran DPC Latency Checker with drivers disabled for Network adapters, Internal modems, Internal sound devices, Comm 1, Printer, Portable Devices G:, H:, I:, and J:, Imaging devices, DVD/CD-ROM Devices, UPS, and Acronic Backup Archive Explorer. The result was latency exceeding 1600 Microseconds for at least one second out of every minute.

I looked at RATTV3, but the documentation said it was for Windows XP and I am using a Windows 7 Home Premium 32 bit OS.

ParetoLogic Health Advisor says one of my drivers is not up to date, but it is a Microsoft driver and Microsoft says it is the latest version. ParetoLogic anti-virus did a thorough check (12 hours) and found no viruses. Zone Alarm finds no viruses.

The system is very slow much of the time and the speakers crackle from time to time. I was having blue screens several times a day, but afterscanning with the Health Advisor they only occur about once a day.

Any ideas about how I can fix this?

I have problem with latency! I have Sony Vaio VPCF12M1E/H laptop with Samsung SSD.
Current OS is Windows 7 x64.

In last two days i have reinstalled OS three times! And still no success.
I have tried running LatencyMon with default OS (microsoft) drivers and with latest drivers from manufacturer.

I have tried to disable many devices in device manager step by step but the problem is still here.

So i guess its not software... Am i right?
It is very annoying! And i cant use this laptop like that! If i watch youtube i hear "clicks & pops" every few seconds. Annoying!

Is there any way to solve this problem?

Hi, hope you guys can help me out.

My issue is that whenever i log onto WoW, my latency is 2.5k or above and as soon as i enter anything, even just jumping around in the cities, i get Dc'ed.

First i thought it was a virus, so i cleaned out my computer and reinstalled everything. I haven't installed any ui mods or addons, fearing that it might have been those that caused the problems.

I'm playing on a laptop, which has a tendency to get pretty hot some times, but i've been playing on it every since i got it in November 06 and haven't really had problems before now.

It's a 2 ghz core2duo, with 1 gb rams and a geforce go7600. I'm playing with a 20 mbit connection, and not on wireless.

What do i need to do? is it my router that is messing things up via a firewall or a port i need to open?

any help is greatly appreciated

A:High DPC latency

Can't seem to edit the thread above, so ill explain here about what happened.

2 days ago I was getting weird popping/cracking sounds coming from my audio, so I googles it and dled dpc latency checker. It was in all green around 300-400us and every once in a while I would get a spike to over 100kus for about 1 second and you can hear the crackling sound in the audio.

Well I restarted my pc and I checked the dpc latency checker and I was getting more yellows and reds than before, so I thought I had a virus or something. So I started disabling/enabling drivers and it didn't fix my problem.

Downloaded nod32 and ran a scan and it didn't find anything. Restarted my comp and now dpc latency checker shows nothing but red in the 10k+ us range. My computer is to sluggish to do anything now.

So I tried combofix and I got BSOD, thought I had a virus yet again. Booted into safe mode and ran combofix and I posted its deletion log in the other thread.

Well as of today im still in the red and have no idea what is going on...

Ok, I have been playin Asheron's Call 2 for about a week now, i had to purchase a new video card in order to play it. I'm only 15 so I got the cheapest one I could find, which was the Radeon 7500. While i'm playing, my latency seems to sky-rocket from my usual no lag rating of 146 to an intensely high lag rating of 200-2000! In my computer, im running 2.0Ghz, 256Mb DDR ram, 40Gb hard drive. The Radeon 7500 has 64Mb of ram and so on if you didnt already know. I've asked many people what to do in order to end my lagging spree which if I may add makes the game very un-enjoyable, some have said to get a better video card, and others have said to get more ram. I just wanted to comfirm with you guys which is need.
