Lackluster Graphics in FFXIV

[Abriael]

No. Pre-rendering is the process in which video footage is not rendered in real-time by the hardware that is outputing or playing back the video.

There are several levels of prerendering.
You can prerender a whole movie, you can preprender just the effects, you can create a scene with an engine and then prerender it with additional effects.

In all those cases a movie is considered prerendered. That tech demo is evidently prerendered, just looking at the effects and how they interact with characters and environment shows that.

The vast majority of posters in this thread has evidently told you that you're wrong. The graphica of the game look fantastic. Even reviewers that you brought up so many times (erroneously) disagree with you.
