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 script which will modify TCPAckFrequency. You will see reduced latency in many online games including World of Warcraft, Aion, Warhammer, Lord of the Rings, and more. System Requirements Leatrix Latency Fix is supported on these operating systems only. Windows XP (SP2 or higher) Windows Vista (SP1 or higher) Windows 7 Both 32-bit and 64-bit versions of Windows are supported. Macintosh users should read the relevant section in the FAQ below.
How It Works Online games generally use the TCP protocol which requires that network segments sent to your computer be acknowledged in order to provide a reliable connection. Windows bundles these acknowledgements together and sends them in pairs. While this is an efficient way of dealing with them generally, the inevitable delays caused by the bundling process increase latency considerably. This is because when Windows queues up an acknowledgement in order to bundle it with the following one, the game server has to wait for the acknowledgement timer to expire before sending new data. Leatrix Latency Fix removes the acknowledgement bundling process so that an acknowledgement is sent immediately for every segment that's received. This produces a significant reduction in latency as there is no longer a delay before new data is sent to your computer. In a normal networking environment, you would prioritise network efficiency over latency and use the Windows defaults, but in online games the opposite is true and you want the lowest latency you can possibly get. Typical Scenario If you could listen to a conversation between your computer and the game server, this is what you would hear. Before Leatrix Latency Fix is installed: Server: "Ok computer, I just sent a data packet over to you, got it?" Your computer: ... Server: "Come on, answer me! I don't have all day! Stop wasting time!" Your computer: ... Server: "Ok, forget it, I've waited long enough, sending another one over! Got it?" Your computer: "Yep, got that one, also got the one you sent before, thanks." Server: "Well, why didn't you acknowledge the first one when I sent it? I was waiting ages!" Your computer: "Sorry, I'm just trying to make the network more efficient by bundling the acknowledgements together in pairs. This is how I'm setup by default." After Leatrix Latency Fix is installed: Server: "Ok computer, I just sent a data packet over, got it?" Your computer: "Yep, send the next!" Server: "That was fast! Ok, here's another, got that?" Your computer: "Yep, send the next!" Server: "Wow! What an improvement! Now that's more like it!" Your computer: "Yep, it's certainly keeping me on my toes, thanks!"

Section 12: Use of Virtual Private Network (VPN) As stated above, the UPC Services are for residential use only and we do not support the use of VPN. If we find you are using VPN we may instruct you to stop using it and you must comply with this request. This is in order to prevent problems with our network and other Internet users.

UPC confirm they have throttling inplace and blizzard have changed they way thier game communicates between your pc and the servers which is behaving much in the same way as P2P does and so UPC is treating the game data as P2P dta..... what this means is that WOW data is given a much lower priority in transmission in the same way as P2P and so the latency and delays in transmitting the game data is causing problems ingame. Virgin Media have the exact same issue which you can check out on thier boards and apparently will have thiers fixed on 9th Dec. Im hoping UPC will be doing the same altho this isnt gaurenteed. If not, bye bye UPC, hello a proper decent isp provider

Not particularly bothered by losing 30Mb broadband if the connection is pissed all over by UPC and their traffic shaping, they can shove it where the sun don't shine. I'd rather a 1Mb low latency dependable connection than this crap.

The only reason people now have an issue with UPC is because they didn't automatically move along with Blizzard in changing something, they are two separate entities and I wouldn't expect either company to be very up to date with each other. I will say that my housemate was on to UPC and they said it's a Blizzard issue, he then rang the premium support line and was told the same thing (by somebody who was not very enlightened about the whole issue to be honest).
