    A latency fixing program by Leatrix

    What does it do?

    Leatrix Latency Fix will reduce your online gaming latency significantly by increasing the frequency of TCP acknowledgements sent to the game server. For the technically minded, this is a program which will modify TCPAckFrequency.

    You will see reduced latency in many online games including World of Warcraft, Guild Wars 2, Diablo 3, Star Wars, Rift, Aion, Warhammer, Lord of the Rings, and more.

    System Requirements

    Leatrix Latency Fix is supported on these operating systems only.
    • Windows 8
    • Windows 7
    • Windows Vista (SP1 or higher)
    • Windows XP (SP3)
    Both 32-bit and 64-bit versions of Windows are supported.
    Macintosh users should read the guide here.

    Installation Instructions

    You can watch a short installation video here.

    Simply download the zip file, extract it and then run Leatrix_Latency_Fix_3.00.exe. When the program launches, click the Install button. You will see the status change from 'Not Installed' to 'Installed'. You need to restart your computer (or disable/enable your network card) for the changes to take effect.

    If you're using Windows Vista or Windows 7 with User Account Control enabled, you will be prompted to confirm that you wish for Leatrix Latency Fix to make changes to your computer.

    Your Windows account needs to have Administrator rights in order to install or remove Leatrix Latency Fix. If your Windows account doesn't have Administrator rights, you will be prompted for the credentials of an account that does have them.

    After Leatrix Latency Fix has been installed, you can login to your online games with reduced latency!

    To uninstall Leatrix Latency Fix, click the remove button and restart your computer.

    For reference, the status line in the program will show 3 possible tags. 'Installed' indicates that all network interfaces have been modified for reduced latency. 'Not Installed' indicates that no network interfaces are modified for reduced latency. 'Partially Installed' indicates that some network interfaces have been modified for reduced latency. You will see this status tag if you add a new network card (or perhaps a USB modem) after the installation of Leatrix Latency Fix.

    Errors and Unexpected Behaviour

    If you have any problems with the program, please click here to send me a message. Include your operating system and service pack as well as any relevant information (such as error messages). You can also try version 2 if you prefer (available here). Version 2 requires the Microsoft.net Framework (available here) but the mechanics are identical to version 3. You can watch a short installation video for version 2 here.

    If you are having problems downloading from Wowinterface, please use this link on Leatrix.com (this link is subject to change so please don't share it elsewhere).

    More Information

    You can find a simplified guide to how Leatrix Latency Fix works as well as an in-depth FAQ covering pretty much everything by clicking here. There is a short installation video tutorial here.

    To ensure that people always use the genuine Leatrix Latency Fix program, please don't publish it elsewhere. It's completely free so there is no need to. Please link to www.leatrix.com instead.

    Thumbs up Very Satisified
    This lil fix is just what the doctor ordered. Normally my latency would sit at 300-330ms. After running your VBS script, latency dropped to 130-140ms, creating a 64% increase in performance from the network.

    Thank you very much for this as it was needed. Better response times from clicks, smoother mob movement, and even less DC's.

    Cheers mate, and thank you again!

    Very nice. My ping went from 70-150 to 11-17 on WoW.

    OS: Windows 7 Pro RTM x64
    (from the MSDN Academic Alliance)
    ISP: Verizon FiOS 25/15

    Code:
               Before  After   Difference
Average     110     14      96
Max         150     17     133

    My results after testing this in Aion.

    I used the command /ping a number of times in a area with few people zoomed-in looking at the floor (low CPU/bus usage).
    OS: Windows 7 64-bit
    NIC: nVidia nForce GBit Ethernet
    ISP: BBB ADSL 24/1

    Code:
               Before  After   Difference
Average     184.6    88.2    96.4
Max         272     125     147
Min         109      59      50
    So my average ping went from 185ms to 88ms.

    Leatrix, I <3 U
    Seriously, I tried manually fixing my ping several times to no avail (with various online fixes). Your fix worked like a charm!

    I live in AZ and my wow server is physically located in Boston, MA.

    I went from a 250-310ms ping to a 125-135ms ping with your fix. I'm operating on a Vista 64 bit SP 2 machine.

    Unbelievably, you've fixed my ping and I appreciate all of your efforts...donation inc!

    Edit: Hmm, seems to be no way to donate to you for your work? Or am I missing something?
