Sema - the registry hack / fix is not the same as the nagle patch implimented into the wow game. So many people believe it to be the same thing... its all wrong misguided information pulled out of context. The registry patch is actually the TCP Ack fix.

Anyway, dunno if you are interrested in learning exactly what the registry hack does, its pretty technical crap in how TCP/IP works. I can try slap something together if you reaaaaally wanna know what the registry patch does but its a crap lotta typing heh.

The registry hack works well but not as well as a game proxy. Although considering my recent suspension I might consider stopping the proxy.

Here is a copy of the original post from MMO-Champion that described how to perform this change manually:

-------------------------------------------------------------------------------------

WoW lags, it's not something new if you're playing on servers a bit far away from your country, but don't worry people are fixing it ! Out of all the methods offered to fix the lag on your machine, one of them posted on Elitistjerks forums seems to work very well.

Read this first 1 - It might have side effects, like slowing down your download speed or affecting your performance on other softwares. (In my case, it didn't change anything)
2 - If you're not sure about what you're doing, just don't do it. I don't want to be responsible because you crashed your computer in some way because you wasted your registry.
2.1 - Seriously, if you don't know what you're doing, don't do it. It will be fixed in one or two weeks anyway. (and the official fix won't have any impact on other softwares)
3 - If you don't have the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSMQ\ directory, you can download and apply this file to your registry.
4 - Windows Vista users might want to check this post too.

"1 - TcpAckFrequency - NOTE if you are running Windows Vista this setting may not have any effect - a hotfix is needed which i'm tracking down. This works fine under Windows XP

Type "regedit" in windows "run.." dialog to bring up registry menu

Then find:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\

There will be multiple NIC interfaces listed in there, find the one you use to connect to the internet, there will be several interfaces listed (they have long names like {7DBA6DCA-FFE8-4002-A28F-4D2B57AE8383}. Click each one, the right one will have lots of settings in it and you will see your machines IP address listed there somewhere. Right-click in the right hand pane and add a new DWORD value, name it TcpAckFrequency, then right click the entry and click Modify and assign a value of 1.

You can change it back to 2 (default) at a later stage if it affects your other TCP application performance. it tells windows how many TCP packets to wait before sending ACK. if the value is 1, windows will send ACK every time it receives a TCP package.

2 - TCPNoDelay
This one is pretty simple (Discussed here)

Type "regedit" in windows "run.." dialog to bring up registry menu

Then find:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSMQ\Parameters

Right-click in the right hand pane and add a new DWORD value, name it TCPNoDelay, then right click the entry and click Modify and assign a value of 1.

Click Ok and close the registry editor, then reboot your PC."

Using a proxy is not illegal ... they actually even stated its ok to use a proxy to channel your traffic.

However some of the proxy service sites are dodgy and lots of goldsellers use them... so avoid using the freeby dodgy ones.

I was kind of a non-believer in this type of patch, due to the fact i was playing on a mac mostly my latency never went over 340-350ms, after getting a desktop, my latency has been nothing short of 490-550, on unshaped 2mbit. After finding this download it is the nagle patch which i believed was built into the code base of the wow client (cant really see how they could achieve that considering its the protocal stack on windows itself, but anyways). I ran this patch last night before the raid, and my latency never went over 350 that was with running vent, and on vent my latenc was 200. There are two vbs files in the zip you download, the one being the application of the registry hot fix and the removal of it. This has been discussed in great length, but this is a better alternative than to running that exe app that does it. Use it dont use it, your choice
