Text question for PSP8.

Okay, I feel really dumb for asking this but I have spent hours and hours trying to figure this out to no avail. I have mastered how to use bitmap fonts and am quite pleased with them but...my problem is with script fonts. I cannot figure out how to use them and make them look nice. When I use the bitmap fonts I create as a floating layer and then do the whole expand thing. I'm wondering if you all do the same for script fonts as well. When I try to do that, since for scripts the font is usually bigger, it looks all pixelated. I can't figure out how everyone gets their fonts to look all smooth and pretty in bigger font sizes. I know this is probably something really simple that I'm missing. I looked in the memories and nothing there answered my question. Can anyone help?
