High Latency since Windows 7

Q: High Latency since Windows 7

Well, I just recently upgraded to Windows 7 Ultimate, I've been loving how sleek and quick it has been until today...

I am a WoW player and also use the internet like any other user and I've been experiencing EXTREMELY high lag spikes at random times. I'll be running along in WoW with my latency around 60ms then I'll get a spike to 4200+ and disconnect...

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...

My roomate is playing on the same network (only using vista) and he NEVER has any latency issues...

Any thoughts? Any help would be appreciated! Thanks!

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.)

Assuming you have the latest drivers for you HP pavillion already installed?

What kind of router are you using, wired or wirless, brand model and version would be helpful.

Have you tried connecting directly to the modem to see if the connection improves at all?
That is one easy way to tell if it's a router firmware or compatiblity problem or not.

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.

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.

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 cannot recall what it was in Windows 7 exactly, but it was much less than 500us. In Windows 8, it never drops below 1000us.

I measured the DPC Latency using the DPC Latency Checker.

Any idea why this is? Immature drivers? (Specs in the sig btw)

This is also on the *leaked* Windows 8 x64 Enterprise. (Don't worry, I have MSDN and am getting the real thing on 15th )

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?

Setup:
Windows 7 x64 SP1
Asus Sabertooth 990FX mobo
AMD Phenom II X6 1090T black edition CPU
8gig ram

Cheers,

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.

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)

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.

Hello!

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.

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:

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.

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.

Well lets start here by asking what type of network card you have and router? Are both up to date with the latest drivers and firmware for the router? Does the router support IPv6? if no on the IPv6 disable it and see if that fixes the issue.

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.

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

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?

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?


Just as an aside it might be Zone Alarm.

Also note, I recently upgraded routers..I had gotten 72Mb/s from old router now I get 150Mbps but I am on a 100Mbps plan. Also could it be that my bro is using ethernet instead of wifi, ever since by performance has gone down the drain. Thanks.

Hi guys,

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

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...

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.

Hi!

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?

Hey there!

I've been struggling lately with my internet connection and I have severe latency issues when I'm playing online games (World of Warcraft in this instance).

We got a new router (from Linksys to Netgear) two weeks ago, and the problems are just piling up. My connection is good, but the internet is very random in speed and according to www.speedtest.net, I only have everything from 5-9 mbps even though it's a 20mbps line. I'm the only one in the house with a pc (three others with Macs) and they don't have any issues with the internet speed.

When I'm logged on to the game I get high latency straight away (500ms to 1000ms) and my trace routing shows the connection is fine. This is really starting to annoy me and I'm wondering if you can help me out with this matter. Could it be that Vista doesn't talk to the router?

Attached is a diagnostic of my PC. My current setup is an i3 2120 cpu paired with a R9 270 GPU and Corsair CX500 PSU, with 8gb DDR3 RAM. The card seems to be performing well according to the FPS (up to and beyond 60fps on bf3 and around 50 bf4 both on ultra). However, gameplay for a lot of games does not feel at all smooth despite the reported fps. This seems to be due to a surprisingly high frame latency (around 40ms when testing with MSI Kombustor), which seems to be causing small (but highly irritable) microstutters at random points, usually every 10 seconds or so, or when having to dynamically render new objects like players or traffic. I was wondering if this is likely to be a GPU fault, or if I simply need a true quad core CPU to reduce the latency? Please get back to me asap, I do not think I can really afford to replace the GPU since I brought it second hand therefore the warranty has expired as far as I am aware.

Recently I had some High DPC Latency which I believe was the cause of some sound stuttering. I believed it was my headset but when my new headset, Sennheiser PC363D, came in I had the same problem. At the time I was unaware of what DPC Latency was and just thought my old headset was dying. When I used my new headset I experienced the same stutter in sound. I never once experienced any stutter in sound when I use my TV, I use a TV as a monitor.

I ended up switching USB ports a couple times and found that I no longer had any sound stutter but I was still experiencing High DPC Latency.

If I am playing music through youtube and teamspeak I experience on average 550 DPC Latency.

If I turn on OBS to stream I experience around 600-700 DPC Latency

If I turn on Steam to play games I experience about 12000+ DPC Latency

Now I know none of this is normal because my friends are running all of this on computers that are not as strong as mine and are averaging 50 DPC Latency, 130 DPC Latency, and 80 DPC Latency.

A:High DPC Latency No Stuttering

I am assuming you are using Windows 7 Ultimate.

1. Forget about "xperf -d %userprofile%\Desktop\trace.etl". That is part of a toolkit for Windows 8. The only reason they suggest using it, is that LatencyMon is not compatible with Windows 8.

2. Download and install LatencyMon from Resplendence Software - Advanced System Tools and Developer Components

3. Download DPC Latency Checker from DPC Latency Checker

4. Run DPC Latency Checker. Note if you are still having high latency.

5. If you area experiencing high latency, run LatencyMon. From there look at the Processes tab and Drivers tab and see which processes and drivers are causing the most amount of latency. If it is a process causing the issue, try ending the process to see if things improve. If it is a driver, try updating the driver.

6. If you need to disable prevent a driver or process from running at startup, download and install Autoruns from Autoruns Download Be sure to run as administrator and be sure you know what you are disabling before you do so. To disable something from startup, just uncheck the box next to the item (do not delete it!).

7. If you suspect a virus or malware, post your problem in Windows 7 Forum - BleepingComputer.com Bleeping Computer is very reliable and would be a great place to help you with such things.

I got windows 7 64bit pro oem with the machine, then I added windows xp home retail version for dual booting. The reason I added xp was because I use a digidesign mbox sound interface for audio production. This interface is not supported on windows 7 (won't install).

I set up the dual booting, installed my mbox on xp, and found that I was getting occasional drop outs with static. So, I downloaded dpc latency checker and found that the latency consistently sits just below the 2000 microsecond mark, with the occasional peak above it (screenshot attached). However, when I boot windows 7, the latency is consistently much lower.

I've googled this and all I got sense of was something called an overloaded node? What does this mean? If any of you out there are internet savvy then I'd really appreciate your help! Thanks!
 

A:High Latency at Night?

What that basically means is that your ISP is overloaded or busy & there are too many users connecting to the same circuit in the local exchange or ISP center
It is extremely common at night when more users are online
There are no cures except switch to a different ISP or type of service but in many areas that doesn't make a lot of difference

The other thing that can happen is that you are unwittingly sharing your wireless connection or it is picking up interference from neighbouring wireless. You can try connecting via an Ethernet connection ( wired) and see if that improves. You will always get slightly better via a wired connection than wireless anyway
