In order to make changes to your Datarate settings please go to your EverQuest Folder(the default location is C:\Program Files\EverQuest\ or C:\Program Files\Sony\EverQuest\) and locate the file named "Datarate.txt". Open this file, and adjust the number from "5.0" to "9.0".
Raising the datarate will cause the game to send your computer larger data packets. Some connections will perform better with larger packet sizes. Many users have also commented that increasing packet size decreases zoning time.
If you notice that the problem is not resolved using the value of "9.0", then try using the value "3.0".
Some users tend to have packet loss on their connections for a variety of reasons. Lowering the EverQuest "Datarate" value will reduce the size of the data packets, allowing more "good" data to come across during a packet loss situation.
Do not use any values lower than "3.0" or higher than "9.0", as the results will be unpredictable, and may cause further problems.
If these recommendations do not resolve your problem please change the datarate value back to "5.0", and contact us for further support.
