[quote=ishtar]Well, with the graphic technology keep getting better, it's logical that graphics and animation of the newer series should be better than the previous. Though... seeing as I haven't play Oblivion (Skyrim being the first of TES game that I played)... 'Oblivion shadow squares'? o-O They use shadow squares for face there?[/quote]

tl;dr: Anti-aliasing hadn't quite made the full jump into procedural (situational/universal) rendering yet. So in certain lighting situations where a light is cast across a person's face, having anti-aliasing enabled on higher settings attempts to smooth out the jagged edges of the face--which causes the shadows to be "smoothed" against the face in a series of squares.

Ergo: Shadow squares.

Later on the technology evolved and shadow layering became a thing, shadow squares disappeared.

Still hilarious to see sometimes though. Almost as good as the characters literally locking up save for their faces when they talk to you, where they stare at you, unwaveringly, [s]raping your soul in their minds[/s] being paranoid.

[quote=ishtar]I'm not sure whether I like the Falmer or not, all I know is that trying to sneak or pass through their territory could be one of the most irritating thing in the... behind..I become quite paranoid whenever I saw their hidey holes on the walls. Never knew when or which one would suddenly spew a Falmer in front of you... or on top of you...

I like them for that reason actually. That sneaking about they can surprise [i]you[/i] in their lairs. It shakes things up from the usual "I'm just going to pick them off one by one and there's nothing they can do" strategy of stealth in Skyrim. I also like that if you stand right in front of a Falmer, even in broad daylight, they can't see you. They're legitimately blind and react to sounds.
