There you will find a list of files named from 0001 to 0032. 0001 and 0002 are the "configuration file" for the ForeGround Resolution (you can see at what resolution you are currently usin FFXI on the right).
To pump your BackGround Resolution you have to change the files 0003 and 0004. Usually by POLOptions you set it up to 1024x1024 only. Just press twice on 0003 and 0004, select "Decimal" and set the new resolution as 1280x1280 (VT computer needed), 1600x1600 (VT computer needed) or 2048x2048 (IT computer needed).
I usually play with 1600x1600 background and have lag only when there is lot of ppl around me (like dynamis or Lower Jeuno AH). Remember to do this operation when you are not logged in FFXI.
