World of Warcraft

For those of you who enjoy end game content of World of Warcraft you’ve probably at least at one point suffered from a laggy connection.  Here’s a quick fix that should seriously reduce your in game latency.  This fix works for Windows 7 / Vista and possibly XP.

  • Open Regedit
  • Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Tcpip\Parameters\Interfaces
  • Find the interface folder that is currently in use. It will be the one that has an IPAddress and the most fields.
  • Right click on the interface and choose New -> DWORD (32-bit) Value.  Name it: “TcpAckFrequency”
  • Right click on TcpAckFrequency, select modify and change the “0″ value to “1″.
  • Right click on the interface and choose New -> DWORD (32-bit) Value.  Name it: “TCPNoDelay”
  • Right click on TCPNoDelay, select modify and change the “0″ value to “1″.

Restart your computer for changes to take effect. If all goes well, you should notice a lower latency while playing WoW.
