At this point, I think it’s a running joke for the Epic staff to allow his crash out over nothing. I’ve been able get Nanite and Lumen running smoothly on the Xbox Series X and S at 60FPS (Performance) and locked 30FPS (Fidelity)
Screenshots captured directly from the Series X running at native 4K with cinematic scalability(I modified the DefaultScalability.ini to reduce the default cinematic quality of course).
I was initially frustrated with the state and lack of proper documentation for Nanite and Lumen, but after playing with it and ACTUALLY BUILDING A GAME with these technologies, you learn a whole lot. Also, the newer version of the engine have brought forth great improvements to all of the technologies despite what KJ wants to say.
You will never understand how to use these technologies properly unless you build a game with them. KJ has been building a youtube channel instead so of course, there is no real knowledge.
