Lowering Latency

[Soullinker]

How
to Lower
your
LAtency

Seeing how much people didn't know about how to set PC priority i was thinking that some people didn't know how to lower there latency.


The WindowsXP explaination can be found here: support.microsoft.com/kb/328890

Those under WinXP, goto start > run > "regedit"

You will need to navigate to this folder:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentC* ontrolSet\Services\Tcpip\Parameter* s\Interfaces\<Interface GUID>

When you are in your Interface folder, you'll find a few folders you can choose from, you need to find the one which represents your Network Interface Card settings.

Generally, it will be the one with all the IP settings, etc. Hopefully its not to difficult to figure out which one it is.
Chances are the registry value isn't there, if it is all is good, just change its Binary value to 1.
If it isn't there, you'll need to create a new one. Right click on some white space and make a new DWORD.
For the name, type in (case sensitive) TcpAckFrequency.
Right click on it, then select modify.
Edit its Binary value to 1.

Note, that its default value is 2 (visit the microsoft page linked up above).

Your computer will require a restart for it to take effect. Please read below about the affect this setting may have on programs other than WoW.

It apparently has an affect on things such as downloads, and P2P where "larger" packets are being sent, apparently WoW uses smaller sized packets. As a result, you may want to change the setting back when you wish to download stuff.
Just do the same steps but type 2(normal) instead of 1

For Vista:

The TcpAckFrequency registry key change can be made to work in vista if you locate and install KB935458-v2-x86.msu for 32 bit or KB935458-v2-x64.msu for 64 bit.

Google it, it seems to be part of the vista sp1 beta and isn't generally available.

It made about 150-200ms difference to my ping, its a whole new world.
If someone with Vista could confirm this, it would be appreciated.

Edit: Searched abit for Vista and this what i found out more:

As i don't have Vista this is untested.
Download the files below and install them. Now Do the steps for Xp Users. For Vista SP1 users there is some kind of problem.So it may not work for you.

The downloads....no need to search them now...
Vista 32-bit – http://mattgadient.mgfileserver.com/...v2_x86.msu.zip
Vista 64-bit – http://mattgadient.mgfileserver.com/...v2_x64.msu.zip

Find out if it helps:

There is not a flashy program to found if this help.
So grab a pen with the normal seting log in WoW and every min right your latency for 10 min every min.
Then do the same with the edited seting.

Found a video: Hear is the link [ame="http://www.youtube.com/watch?v=9_hVwD91D7w&NR=1"]YouTube - Latency Reducer - Warcraft[/ame]

Soullinker I am planning on flaming you again, simply because you deserve it.

---> This thread uploads a file that does just this.

on the bottom of the first page you can also find:

I wouldnt recommend to download this. You don't need any program for this.

Just use this guide: (my latency dropped from 200 to 50, everything happens now instantly, its really imba) after doing that, restart computer OR just boot your network

YouTube - TcpAckFrequency tutorial

--> Which is the same/almost the same video, I bet you even got it from that thread and reposted it on purpose...

And if you are saying that you did not know about that post, then you are simply horrible at using the search function since searching for "latency" which is the main thing in the post will give you that post so gtfo.
