Why can't devs deliver a "Next gen" graphics moment with PS5/XSX?

The PS5 is only about 5x the GPU performance of the base PS4 so you can’t expect miracles.

I think too many devs expected 30 fps to continue being the norm on consoles and used that as a target when they began development. At that frame rate you usually get good image quality.
