MLAA doesn't blur the image. It's the visual perception caused by rounding the edges that should be rectangular. And it affects the fonts in some cases. What they use here is FXAA 4.x or possibly 5.x developed by one of their engineers Timothy Lottes who also runs a blog about it here:

There is also a 3rd method with lots of potential, called SMAA. You can find it here:

What i hope here is that NVIDIA will give possibility of using their nFXAA (see what i did there
) the same way as AMD does with their MLAA. So you can enable it for any game you want through drivers. Because injecting FXAA or SMAA into apps does work but is incompatible with any kind of multiplayer game that uses anti-cheat system. MLAA on the other hand is immune to this problem and can be freely used in ANY game.
Because if they do that, i'll seriously reconsider buying a Kepler based gfx card even though i have HD6950 at teh moment. And MLAA is great but i know it has limitations nicely shown by the SMAA guys in their tech video. On the other hand i won't consider Kepler in case if AMD can give us FXAA or SMAA along with existing MLAA just by Catalyst update. Because if they do, i'll have another reason to stick with Radeons. Yeah, this feature is that important for me, because there are loads of games ported from consoles and no one cares about adding some FSAA to them. NFS Hot Pursuit 2010 was one of such games and while many complained about the lack of any kind of FSAA, i just enjoyed it with MLAA and i still do. No jaggies at all thanks to MLAA in Catalyst.
So yeah, NVIDIA, bring it on. The more they offer such techniques, the better. So we, the customers have more options to chose from.
