We admit: it's a confusing subject. The concept of high definition and resolutions appears simple on the surface, but once you delve deeper, things get far more complex than you may have initially expected.
Fansite FF-XIII.net reported that the Final Fantasy XIII demo might support native 1080p resolution , although there was the admission that the game rendered in 720p. Well, UK site GameZine has cleared the air: the demo runs at 720p with 2xMSAA, and that's all you need to know. …no? Well, here's a bit more from the explanation:
"This resolution and its included anti-aliasing, which removes "jaggies" by adding an intermediary shade between polygon edge steps, still results in a very clean image. The quality of the demo's in-game graphics truly show off how great an engine Square Enix has created for the PlayStation 3 game."
Furthermore, even though the game itself will run in 720p, the CGI cutscenes will suport 1080p, which is a "mixed resolution that many games will begin to take up on the PS3." In turn, we have to understand that these max-HD cutscenes will take up the majority of the space on the Blu-Ray disc but also, it begs the question: how will this work on the Xbox 360 version? Well, that's not for us to say. We'll leave the technical stuff to the developers.
