I’m not too convinced from trailers coming from a huge PR show, even a bit sceptical. While it would be nice if they find new technologies, I have my doubts. There have been too many lies in the past, so until I play the game for myself and see that their engine does what they promised, I won’t applaud anything. (Unless they talk about it, like at GDC)
As far as I understand it, many of these engine are made for specific cases and are not generic usable like UE4. Sometimes they even come with limitations in some form or another. What I do have to admit is that the effort put behind them is astonishing, many implementations are based on clever tricks since they had the need to find some way.
It feels like many technologies powering engines running on consoles have more effort put into them (since console sales are a huge), while on PC we end up with more or less brute-force attempts.
Anyways, it’s nice to read these posts, while I have to believe they are true, many informations mentioned are interesting and I do hope that someday I can talk alongside you properly ^^
