On the fourth page 3rd paragraph after the first slide, I think they are talking about spherical lights being more physically correct and less prone to specular aliasing than point lights, but it's badly translated, so I'm not sure...
Yeah, its in some way Area Light, but not at the degree of KZ:SF or Crysis 3. Its mostly for specular component.

That's interesting.., one of the first times I've seen a relatively direct comparison between PC and PS4/XbOne in that way.
Its not completely relative, because 570 [and i7] was outperforming PS4 in this demo.
