    If you're like me and play games on-line on your PC you'll be looking for ways to reduce your network latency.

    Most people are familiar with the Leatrix Latency Fix which was posted on the wowinterface site, but recently I happen upon another site which details a further tweaking which includes the aforementioned Leatrix fix along with enabling TCPNoDelay.

    Allow me to share the fruits of my googling

    Taken from LifeAndCode
    1. From a command prompt (usually in All Programs -> Accessories -> Command Prompt) run “regedit”
    2. Browse to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\servic es\Tcpip\Parameters\Interfaces
    3. Browse the items under interfaces until you find one that has an IPAddress entry matching the network interface you want to affect (typically LAN IP addresses start with 192.168 or 10.0); note that if your IP address is automatically assigned by a DHCP server you may need to look for a matching DhcpIPAddress instead of IPAddress
    4. Right-click on the interface and select New > DWORD (32-bit) Value, name it “TcpAckFrequency”
    5. Right-click the new TcpAckFrequency value and select Modify, enter “1″ (Hexadecimal radio button should be selected)
    6. Right-click on the interface and select New > DWORD (32-bit) Value, name it “TCPNoDelay” (note that TCP is all uppercase this time – that’s intentional)
    7. Right-click the new TCPNoDelay value and select Modify, enter “1″ (Hexadecimal radio button should be selected)
    8. Verify that both TcpAckFrequency and TCPNoDelay now show up in the adapter’s property list with types REG_DWORD and values 0×00000001
    9. Exit regedit and reboot (reboot is necessary for the changes to take effect!)
    10. Play a game and enjoy your new low ping
