Latency Issues after upgrading to Windows 7.

[Volumes]

Hey guys, I've been having some issues with latency issues recently. It all started after upgrading from Vista to Windows 7.

I have tried upgrading all my drivers, and even downgrading my Network driver thinking it might fix the problem, but to no avail.

I am a big online gamer, so you can understand the frustration. My ping sits around 19-20 but will spike up to anywhere between 50-80 for 5 seconds, then back down. This happens every 15-20 seconds or so.

I've left DPC Latency Checker running while I disable both my audio drivers, with no change, as well as my Network driver, and the issue still persists.

Any help would be greatly appreciated ! I don't know what more I can do at this point.

This issue is definitely on my end, because my desktop computer has no latency issues, so I don't believe it is my ISP, and the issues didn't start till I upgrading my OS.

I suggest you run Process Explorer and check which strings are involved (from Properties).

The picture is supposed to give you an idea, but at this time I have no DPCs.

This is what I got, not sure if it's what you're looking for. I'm just learning all of this stuff, so you might need to explain somethings.

This is the System Idle Process - that does not help. You have to look at the DPCs like on my pic.

 

[Volumes]

I do not have a tab next to system idle process like you do in the picture. There is no DPC column in my process explorer.

I must be missing something.

this is the only thing I see with DPC.

Hi,

Experiment with disabling IPv6 in Win7. Although I don't think this is actually your problem, I suspect the upgrade may have messed with your network stack. Disabling IPv6 (via the properties of your network card) will force Win7 to rewrite the options stored in your registry and may solve the problem.

If that doesn't work, just uninstall everything to do with your network card, and reboot. Windows will reinstall it all. If you are using an onboard Nvidia card, you can download and install the latest nvidia chipset drivers which also may resolve the issue.

DD.

I've tried disabling IPv6, no dice!

I'm going to uninstall the network driver and reboot, see if it works.

Be right back

Well I uninstalled the Network adapter and rebooted, still no fix.

anything else I could try? this problem is so frustrating.

Sure, but these will be guesses.

- Go into your NIC properties, Power Management, ensure that "allow the computer to turn off this device to save power" is NOT selected.
- Go into the Advanced settings, and turn on Flow Control (or turn it off if it is ON). I would normally advise to have it off when online gaming, but turning it on may give you a more consistent latency rate.
- Ensure "Interrupt Moderation" is off.
- Try different duplex settings. This setting can have a big impact on latency, and it is not always obvious which one to choose. By default, you probably have it set to auto-negotiate. Normally you would want the fastest full duplex available for your NIC, but I have seen instances where setting it to fastest half duplex greatly improved ping times.

Good Luck!

Was this a clean install or did you Install on top of Vista?

 

[Volumes]

This was installed over Vista.

Start updating drivers of everything, from soundcard, nic, video, etc.

I've updated everything I could.

Do you think performing a clean install could fix the problem?

Can you clean install from a USB, or does it have to be a CD?

 

[Anthony]

Always do a clean install when you can to avoid issues like this, its always easier to track down any problems (if any) after a clean install. It only takes 10mins to install from a USB Stick!!

So, I did a clean install, updated all my drivers, and I'm still having latency problems.

Specifically with a game called League of Legends, if that makes any difference.

Did you try those Network changes I posted above?

 

[Volumes]

Those setting are for a wired ethernet connection im running wireless right now.

and I had no problem staying at a constant 19 ping with no spikes, wireless, while I was on Vista.

Ahhh, didn't realize this was wireless!

OK, that may actually make it easier. Have you tried this :

Control Panel -> Power Options, click "Change plan settings" for whichever power plan you are currently using. Then "Change advanced power settings". Scroll down until you see "Wireless Adapter Settings" and then "Power Saving Mode". Change whatever it is to "Maximum Performance".
