Normal anti-aliasing works fine on CRTs, that should give you a
better images than turning on sub-pixel anti-aliasing.
The point of the source I read was that the sub-pixel algorithm is
very nearly doing the right thing on CRTs too. I realize that it doesn't
achieve the same results, but it's good enough that there's not much
reason to implement two different solutions -- if sub-pixel is on all
the time, it performs extra well on LCDs and more or less the same
as anti-aliasing on CRTs.
That also had examples and an explanation, but I haven't found that
page (it might be on the same site, though, as the pictures look the
same to me).
Of course, this was kind of a footnote -- the whole point of the
sub-pixel technique is to look good on LCDs.
Cheers,
Terry
