Impressive showcase, but this is just the surface of what the engine is capable of...
its an environment with a single character, some light source and there is environment creatures.
so far from the video they show case how pretty light source can be and how beautiful the 8k environment textures are.
I think the latest pc spec can run this at 60 fps no problem..
but they didnt show for example like the character walking through a market where there is multiple characters around
tons of things to render for example, stalls, food, shadows, ai walking around in the back.
this will definitely require more cpu/gpu to run
