Yes it is Squall. MLAA is a smart filter that's what makes it different vs a box or tent filter like AMD had before. MLAA uses an algorithm to determine edges and then applies a blur selectively to those edges. It doesn't work at all on subpixel objects as it cannot detect those edges smaller then a pixel. It cannot reconstruct geometry that doesn't already exist and it sometimes chooses an edge that isn't an edge but it's not a dumb filter. It's a smart/selective/adaptive filter.

The problem is the way edges are defined. My guess is that edges are defined to be rough transitions between colors (say white to black or yellow to dark red, etc). So if the scene contains a lot of rough color transitions, MLAA will be applied to the whole scene. This is especially noticeable with texts.
Anyways, I forced MLAA on and tested 3 PS2 games. To my surprise, it actually looks good with PCSX2. Good AA with minimal performance hit.

Yeah each version of MLAA seems to do that differently. Though the general consensus is of course the better algorithms for finding the edge are more expensive. I know one of the cheaper ones is to use luminance which is basically brightness. So that tend to use sharp contrast between light an dark get a lot on edges detected while games that are mostly midtones don't.

Yes it is weather you want to believe or not is another matter and no I wish though. Just a coder monkey with an interest in tech including graphics tech. though you are somewhat right it was designed to be run on the framebuffer before the HUD has been applied as it's 2 major downsides are it doesn't do anything to subpixel objects and it can make text look really bad if applied to it.

I'm sure it works for any games, but the ones I tested were Rouge Galaxy, Gundam vs Zeta Gundam and Fate/Unlimited.
