CD PROJEKT RED has released Cyberpunk 1.62 update 2077 with Ray Tracing: Overdrive Mode technology that enhances the game's already impressive renders. This new update enables full ray tracing rendering, also known as path tracing, which accurately simulates light throughout the game environment. This technique is also used in the film industry to create special effects indistinguishable from reality. Until now, real-time rendering in full ray tracing was impossible due to its demands on GPU resources. However, nVidia's AI and DLSS have succeeded in changing the situation.
Previously, separate techniques were used for ray-traced shadows, reflections, and global illumination for a small number of light sources. With full ray tracing rendering, the properties of light emitted from a virtually unlimited number of sources are modeled, resulting in shadows, reflections and global illumination physically correct on all objects. This technique is still in development, but it is a taste of what will be the future of full ray tracing rendering.
The different rendering pipelines illustrated
One of the most significant additions to Cyberpunk 2077's Ray Tracing: Overdrive Mode technology is nVidia's RTX Direct Illumination (RTXDI), an SDK that allows developers to realistically reproduce light in scenes with many sources. bright. With RTXDI, thousands of objects can emit ray-traced light. In Cyberpunk 2077, every neon sign, street lamp, neon sign, car headlight, etc. is ray-traced, resulting in precise illumination of objects, walls, moving cars, and more. pedestrians.
By enabling Ray Tracing: Overdrive Mode, light sources now all cast soft, physically correct shadows, something previously unimaginable with older rendering methods. Players benefit from improved shadow rendering, with more depth, detail, and realism.
