Windows 7: Latency Issues after upgrading to Windows 7.

Latency Issues after upgrading to Windows 7.

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.

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.

Hi,

Experiment with disabling IPv6 in Windows 7. 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 Windows 7 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.

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.
