Last week Square Enix announced Final Fantasy VII Remake Intergrade, the new PS5 version of last year’s hit, which adds an exclusive chapter starring fan-favorite character Yuffie. As we’ve recently seen demonstrated, Intergrade tweaks and improves the RPG’s visuals and performance, but according to director Tetsuya Nomura, we’ll have to wait until Final Fantasy VII Remake Part 2 to see the full range of the PS5's features taken advantage of.

Lighting and textures are the main adjustments for [Final Fantasy VII Remake Intergrade], but environmental effects such as fog have also been added to further improve the sense of presence and immersion in the world view. […] As for adaptive triggers, they are partially supported. However, in terms of using all of the features of PlayStation 5, please wait for the next game where we can start from scratch.
