*My english is not perfect cuz I'm not from english speaking country so just understand it please

I've been reading through the posts at this forum but I haven't found proper solution.
I've got windows XP and ATi Radeon. A few days ago, I installed Nvidia patch and the game graphics got far better. But the problem is, when I enter the world map or get out of world map(like getting into town, menu, or battle), there's loads of hard disk swapping. It takes really long so I can't get on with the game.
I think it's not because of free hard drive space cuz I've got more than 20GB left. Does anyone know good solution for that? I really need your help. As a reference, I've installed XP chocobo race 1.02 patch, too.
