Leatrix Latency Fix  Popular! (More than 5000 hits)

Version: 3.03
by: Leatrix [More]

Introduction

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, WildStar, Heroes of the Storm, Elder Scrolls Online, Guild Wars 2, Diablo 3, Star Wars: The Old Republic, Rift and more.

Note that Leatrix Latency Fix performs a different modification to the 'Optimise Network for Speed' setting in World of Warcraft. They are not the same thing and can be used together (more information on this in the FAQ).

System Requirements

  • Windows 7, 8, 10, Vista (SP1+) or 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.x.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. After that, you can login to your online games with reduced latency.

Your Windows account needs to have Administrator rights to run Leatrix Latency Fix. If you are using Windows Vista or higher and your account doesn't have Administrator rights, you will be prompted for the credentials of an account that does have them.

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 USB modem after the installation of Leatrix Latency Fix).

Errors and Unexpected Behaviour

If you have any problems, please click here to send me a message (include your operating system, service pack and any relevant information such as error messages). If you are having problems downloading from Wowinterface, please use this link on Dropbox (this link is subject to change so please don't share it elsewhere).

More Information

There is a FAQ covering pretty much everything here and 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.

EDIT: Make that 15-45.

Just wanted to chime in, I'm on Vista 32 sp2 and after running an earlier version of Latency Fix (I'm pretty sure it was when you first uploaded it here under a different name), I went from 300-400 ms down to 70-110ms in Dalaran as well as in 25 Man Trials and Uld.

I have a link to LLF on my UI page and often recommend it to guildies and friends. Thanks for helping out the community, it's really appreciated.

from 400 to 80. The cynic in me is telling me that this is too good to be true, but you actually solved all my latency problems in one swift stroke. Thanks a lot.
