It's not so much sharper as narrower. Which means you can push it up a
bit without making the whole thing look mushy. If that makes any sense.
It's a steeper falloff.

Mostly I just use min -1 and max 2. and box filtering 1 or
sometimes I
use triangle 2 for a softer effect.
I output a string of 852 x 480 bmps to my clients and then they
mpeg it
somehow and wack it up on big plasma screens. They never complain.
When
they want stills for print I just render a frame out huge (3000+)but
leave the antialiasing the same.
If it's for telly I do HD res. If it's to be comped with live action I
ask what anti aliasing they want.
