I wanted to give a quick example to further illustrate the point I was making about 'labels' in judging the quality of different lighting approaches.
Which of the games above has better lighting?
Assassin's Creed 4 uses a form of "global illumination", while Killzone Shadow Fall is using image based lighting with physically based rendering (which is basically the same setup as The Witcher 3 is using).
I know both games can look better and worse than the screenshots above, but having played through both games I think I was more impressed with the lighting in KZ Shadow Fall more often than the lighting in AC4 (although I loved the day-night cycle).
I hope this makes it clear that we can't judge the quality of a lighting system in a game simply by the label that is slapped on it.
