I'm extremely comfortable with how they used AA in this game. I mean, it doesn't bother me, disturb me, make me awkward in any way looking at those pics because there is no blurriness, in any version. The vegetation on the 360 looks better, while the AA on the PS3 hides the jaggies on the sword more efficiently, though the whole image looks softer on the PS3 maybe because of the low AF, or half res textures. It'd s matter of tastes but neither of both versions hurt when looking at them or look blurry to me.
Perhaps the AA they are using isn't FXAA but this superior new technology called SMAA, which sebbbi :smile: mentioned more than once here. It's a relatively recent approach and it looked certainly better than FXAA to me.
