I have seen Cyberpunk 2077’s new “Overdrive” Ray Tracing mode and it adds the following.
- NVIDIA RTX Direct Illumination (RTXDI) gives each neon sign, street lamp, car headlight, LED billboard and TV accurate ray-traced lighting and shadows, bathing objects, walls, passing cars and pedestrians in accurate colored lighting.
- Ray-traced indirect lighting and reflections now bounce multiple times, compared to the previous solution’s single bounce. The result is even more accurate, realistic and immersive global illumination, reflections, and self-reflections.
- Ray-traced reflections are now rendered at full resolution, further improving their quality.
- Improved, more physically-based lighting removes the need for any other occlusion techniques.
