PD build it from the ground up to support native 8K, 120 fps, 10 bit rec.2020 up to 10K nits, from source textures all the way to the end result. It's made ready for ray tracing, yet since the ps4 doesn't have that it was using pre-rendered lighting, shadows and reflections instead.
I see. Pretty neat stuff. Thanks!
But I have a question. In the past (Pre-PS4 gen), developers use to say that a system's architecture dictated what they could or could no do. For instance, PS1 got more 3D games than Saturn due to the unique abilities of the machine. Same for Xbox 360, due to the difficulties of working with the Cell processor. So what's changed? How are these people able to develop for consoles without knowing the full specs? That's what I'm not understanding. Has the way these companies built their consoles changed so something like that is possible?
