End your wow lag. Forever.

This works. I, and some friends of mine got from 600ms to 10 ms. And i havent had a single lagspike since then

To get low pings with 2 simple registry hacks do the following. You need to apply both registry changes to get the maximum effect.

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.

I have found the performance to be at least as good as routing via a linux box, possibly better.

WoW Forums -> Howto: Reduce your Latency

arent this the same thing?

Yes, its the same thing.

I would belive this info should be shared, as it is possibly the most insane thing agaisnt lag ive ever seen done

[Zore.]

Confirmed went from 328ms to 327ms!!!!!!!!

[deathklaw]

well

i didnt check before hand..

but
mines at 320 and apparently everyonee else is lagging bad so :S

who knows

[treyska]

funny thing is, WoW has introduced a compressor on latency.

there have been articles about it on MMOwned recently - it's actually to your advantage to PvP with yellow latency rather than with green.

however, this WOULD come in handy if you're more interested in PvE. and if you simply hate lag altogether :P
