This technique is especially beneficial when applied to irregularly-shaped or translucent objects, like foliage and fences. Opacity Micromaps - Accelerate ray tracing workloads by encoding the surface opacity directly onto the geometry, drastically reducing expensive opacity evaluation during ray traversal and enabling higher quality acceleration structures to be constructed.Shader Execution Reordering (SER), which reorders and parallelizes the execution of threads that trace rays without compromising image quality.Luckily, the upcoming Ada Lovelace GeForce RTX 4000 series GPUs will introduce NVIDIA DLSS 3 and a bunch of hardware and software enhancements that specifically target advanced ray tracing workloads, such as: Needless to say, Ray Tracing: Overdrive will be more taxing than regular ray tracing techniques on existing GeForce RTX hardware. Here at CD PROJEKT RED, we are very proud to be technology innovators, and DLSS 3 gives us meaningful performance gains to tackle the addition of even higher levels of ray tracing to deliver a visually rich experience for our gamers. Jakub Knapik, Art Director at CD PROJEKT RED, said: Improved, more physically-based lighting removes the need for any other occlusion techniques.Ray-traced reflections are now rendered at full resolution, further improving their quality.The result is even more accurate, realistic and immersive global illumination, reflections, and self-reflections Ray-traced indirect lighting and reflections now bounce multiple times, compared to the previous solution’s single bounce.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. ![]()
