>I always thought the biggest difference was subpixel vs grayscale anti-aliasing.

It's mostly hinting. Windows actually doesn't do subpixel antialiasing in many applications anymore. (such as Start menu or new Settings panel)

Of course it does.

I don't understand why you write an incorrect comment when checking whether GP is right takes literally seconds in front of a Windows box (open start menu, screenshot, enlarge, clearly not using subpixel AA).

[danybittel]

It's because that is exactly what I did. And the text in my Start menu has AA? I'd be really surprised if any text doesn't have AA.
