Huh? This is what i meant, there is only one CGI that we've seen so far - its opening after chapter 0. All other cutscenes are on in-game engine.
Just to be clear so there is no confusion:
-FMV/CGI cutscene = scenes rendered in much higher quality, impossible to be rendered in real-time on consoles(or would run very poorly)usually done by a separate team from the in-game programming stuff.
-Pre-rendered cutscenes using in game assets = pretty much uses the assets you see while playing the game(character models and environmental assets)either as they are or slightly bumped up because it's cheaper and easier than letting the console run it real-time. these scenes are just videos being played but can fool you in thinking they are being rendered live.
-In-game cutscene = what the console is actually computing in real time.
XIII had very few in-game cutscenes.
I think it IS safe to say, like you said, that all other cutscenes we have seen in XV are in-game.
To further clarify what I see as a cutscene: anytime you are not playing the game but watching it, having no input or except only pressing a button to advance the pre-set dialogue if text scrolling is present.
