G'afternoon jkun and welcome to the forums!

there are 2 maximizers.. the stand-alone one and keyclone's built-in maximizer.

with keyclone's maximizer, you also get 'commands' allowing you to configure a command per clone.. along with individual fps settings

the maxfpsbk setting it probably where you will get your biggest gain. setting this to 10 or 15 while your maxfps is set to 40+... will resolve most of your lag issues. (to see your current fps.. the default key within wow is ctrl+r)

if you have any other questions or comments, please feel free to drop me a note.

have a great day and welcome to multi-boxing
