Re: Latenfy Fix Results

Before: Anywhere from 275 to 375 MS depending on what dungeon, raid or zone I was in.

After: Consistently 124 MS no matter where I am.

This with no significant drop in frame rate.

Windows XP SP3
Intel Core2 Duo CPU [email protected] 2.8 GHZ, 3.2 GB RAM, Nvidia GeForce 9500 GT (512 MB RAM)

BTW, there is a note that this fix works better if you are hooked directly to your router, however I have seen the above results even though I am using a wireless hook up in a different room across the house from where the router is.

If your web page hit number has gone up in the past few days it's my fault, I've been telling everyone I know in the game about this great little utility.

This is amazing!
Before : 800-1800 Latency.
After: 55-66!

HUGE performance increase, I will be applying this to all the wow computers in the house.
This is just standing in Dalaran too! I'm excited to see the raid and dungeon improvement as well.

Thanks a ton!

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.

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!
