Really? From the way I understand it, using scanlines has more overhead than without.
This is rather noticable in MAME.
My personal opinion
is that scanlines are truer to most older games actual look. IE. running a game on a pc monitor and the same game on a tv (where it was designed to play), the monitor doen't appear accurate. Everything looks blocky; scanlines seem to add resolution rather than detract.
Again this is my opinion.
