The option you mention is on XP. The most similar thing on W2K is
"Smooth edges of screen fonts". Its help text starts with:

"Specifies whether to smooth edges of large fonts to make screen fonts

I'm not sure this has something to do with anti-aliasing, but turning it
off makes no appreciable change on font rendering speed.
