Path Traced settings that will be much harder to notice in standard play are Path Traced Foliage subsurface scattering and full-resolution RT reflections. On the note of reflections first ...

Subsurface Scattering, for more realistic skin, and Screen-Space Shadows, for more shadows on both faces and distant objects. For an example of the difference those can make, I've put together a ...

The game employs comprehensive ray tracing techniques, which include the simulation of sun shadows, global illumination, and subsurface scattering. These features contribute to more realistic ...

The scattering angle provides additional information about the spatial arrangement ... ICISS, analyzing multiple collisions, reveals subsurface atomic arrangement, relevant for catalysis, corrosion, ...
