Leatrix Latency Fix 
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, 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 7
- Windows Vista (SP1 or higher)
- Windows XP (SP3)
Macintosh users should read the guide here.
Installation Instructions
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.

Change Log:
3.00
3.00
- Rewrote the program from scratch using Python. As such, the .Net Framework is no longer required, WMI is no longer used and the program has User Account Control and admin rights detection built-in.
- Leatrix Latency Fix is now bundled with it's Python configuration files inside the download.
- The mechanics of the program are the same as the previous version. If you were previously using Leatrix Latency Fix 2.x or 1.x, the status line will probably show 'Installed' by default.
- Added an exception catcher to the initial WMI code which should prevent unhandled exceptions.
- Updated the FAQ (near the top) relating to WMI errors.
- Simplified the WMI structure.
- Leatrix Latency Fix will now only tell you that you need to restart your machine, it will no longer do it for you. This is to give users more control whether they want to restart their machine or their network card (doing either has the same effect).
- Leatrix Latency Fix is now an executable program written in Visual Basic. It requires Microsoft .Net Framework 4 to run. The system requirements (on the main page) have been updated.
- Changed the restart process for greater compliance.
- Just a few cosmetic changes. To avoid confusion, the checker script will still show the number of adapters modified by Leatrix Latency Fix but will no longer list unknown adapters.
- The Checker script will now show the names of the network interfaces which Leatrix Latency Fix is installed on, and it will show virtual or DHCP addresses correctly.
- The Checker script will now show which network interfaces Leatrix Latency Fix is installed on. It'll list them by IP address.
- Added support for batch mode. You can now run Leatrix Latency Fix from your own batch files. Just use 'cscript <script name.vbs>' in your batch file (eg. 'cscript c:\install.vbs'). Batch mode allows you to integrate Leatrix Latency Fix into logon scripts and automated Windows setup scripts. You must be logged into your computer with an Administrator account to use batch mode.
- Added a checker script which will simply inform you whether Leatrix Latency Fix is installed or not.
- Added support for User Account Control.
- First release.

Aside from what Dolby has already said, this download isn't even compiled. All of the source code is available to anyone that wishes to view it; they're VB scripts. I encourage anyone that knows what they're looking at to review them. You should find nothing out of the ordinary.

I would just like to confirm WoWI has tested this file extensively and it is safe.
The files are vbs so you can look at the source, nothing is hidden. 40 other virus scanners confirm that this is safe: http://www.virustotal.com/analisis/2...771-1271413814. All files uploaded to WoWInterface are manually checked and executable files are held to even a higher standard and are pulled apart in a sandbox before made available to download.

Amazing.
I had around 300ms before LLF and it dropped below 100ms after installing it. Used to be (1y4m ago) below 100ms all the time but now there are three computers instead of one connected to the same router. (a bit offtopic, yes) Oh and.. Win 7 64bit

Re: Great!
Holy mother of Jesus and all the rest of biblical creatures!
This actually works. It's like one of those ''GZ YOU WON,CLICK HERE FOR 1.000.000$ REWARD'' things that actually is not a scam  I got win xp pro sp2 (home edited) and it works from ~170- ~230 down to ~45 - ~80. If i could,and you would be a hot chick,i'd kiss you!

Great!
It really does work =) Just wanted to put this here. I was worried when my computer restarted a bit slower than normal, but I don't think this was the culprit. WoW runs with around 60ms of latency now.
