In reality, sunlight bounces, increasing the illumination of nearby surfaces and objects. Furthermore, the color properties of surfaces are absorbed and added to bounces, so for example, bright light bounced from a red wall to a white tiled floor would feature a tinge of red.
Recreating this effect in games requires ray tracing, and by setting the Ray Traced Lighting option to ‘Psycho’ you can enable it in Cyberpunk 2077.
This effect is applied exclusively to light cast by the sun, with one bounce. It’s demanding, but if your system’s got the headroom to enable it, you’ll experience next-level realism and fidelity.
