It's a laptop? then sorry no matter what you can't run at better setting even if you have a 330m it still a laptop vs a real video card. You would need to waste a big amount of money to play at very good setting with a laptop.

With 450gts it's around 100$ and could run the game on pretty high-setting you could easy build a desktop for about 500$ that can run the game on high setting without issue. but there pretty much noting you can do for that laptop.

Also a note CPU have noting to do with ffxiv it all run on GPU memory which you don't have a good one my gf played on a dual core and play high setting without issue.
