Wow uses 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 Wow the opposite is true and you want the lowest latency you can possibly get.
7 years later and you're still struggling
I liked the other post by Yster, ages ago he reckoned 400-600ms would be way more than good enough to play with. But we've all gotten a lot more demanding since then.
It irks me watching videos of guys playing Overwatch with their 5-50ms pings :/
Well I'm not struggling bud. Have I ever? I mean, I had to carry you for how long?
But in all honestly, how can 400-600ms every be playable? You cast and then wait a bit for things to happen?
Back when this thread was made I considered below 250ms to be playable, but prefered +- 200ms when you are a serious raider.
You already at a major disadvantage being from SA as you are playing with and vs (pvp) people with 5-50ms for the most part.
So much of wow raiding / dungeons is about position, moving and dodging things and latency affects that.
