Okay, so I have had trouble getting FFXI to running properly on my 13" 2011 Mac Book Pro via bootcamp. The main issue being that character sprites don't load up when you start the game.
The problems lies with the Intel HD 3000 graphics card. Unfortunately, the 13" MBP only has the Intel HD 3000 card where as the 15" and 17" have an alternate graphics card that can be used if necessary.
The fix for this is rolling back the Intel(R) HD Graphics Family driver to version 184.108.40.2066 (I found the file from the files provided in the drivers disc you create before installing Windows via bootcamp)
For anyone who aspires to do the same, I hope this help!
