AI-Powered Shaders
- RTX Neural Shaders: Develop and implement neural networks inside shaders to provide novel approximation and compression methods for the creation of next-generation assets.
- RTX Neural Texture Compression: This AI-powered technique uses runtime block compression to compress textures with up to 8x VRAM improvement while maintaining visual accuracy.
- RTX Texture Filtering: This technique reduces artefacts and enhances image quality by randomly sampling textures after shading and filtering challenging volumes.
- Film-quality assets may now perform in real-time to RTX Neural Materials, which use AI to condense the shader code of intricate multi-layered materials for up to 8X quicker material processing.
- RTX Texture Streaming: A tool that effectively manages and loads textures according to demand by breaking them up into smaller tiles.
Geometry and Lighting
RTX Mega Geometry
Improve efficiency in extensively ray-traced scenes and enable up to 100x more ray-traced triangles by speeding up BVH building for cluster-based geometry systems.
RTX Dynamic Illumination
The most significant lights in a scene are sampled using a library of importance sampling algorithms, which produce physically accurate results.
- ReSTIR Direct Illumination: Lighting from multiple lights in one bounce without complicated data.
- Multi-bounce indirect lighting paths are resampled in ReSTIR Global Illumination.
- ReSTIR Path Tracing: Enhances image quality by sampling the most significant light paths.
RTX Global Illumination
Scalable method for calculating indirect illumination with several bounces.
- Neural Radiance Cache (NRC): Utilize AI to forecast the quantity of light emanating from or travelling through a certain region.
- A quick and scalable method for calculating light in a specific area is the Spatial Hash Radiance Cache (SHaRC).
- The probe-based Dynamic Diffuse Global Illumination (DDGI) system provides multi-bounce indirect illumination without the need for lightmaps or baking.
NVIDIA RTX Path Tracing
In order to create a real-time route tracer, NVIDIA RTX route Tracing (RTXPT) combines years of best practices in neural graphics development and real-time ray tracing.
NVIDIA Real-Time Denoisers
A collection of denoisers made to operate with signals that have a low ray-per-pixel.
- Denoise diffuse and specular signals with ReBLUR.
- SIGMA: Shadow denoise.
- Reduce noise in RTX Dynamic Illumination signals by using ReLAX.
NVIDIA Opacity Micro-Map
Improve ray tracing speed by effectively mapping complex geometries onto triangles and encoding their opacity.
RTX Memory Utility
Acceleration structures are compressed and sub allocated to lower memory usage.
RTX Character Rendering
A collection of instruments for producing path-traced, stand-based skin and hair.
- Subsurface Scattering (SSS): Provide skin with precise translucency and illumination.
- Blackwell accelerated sphere and curve primitives for strand-based path-traced hair are known as linear swept spheres (LSS).
- For strand-based hair, the enhanced analytical Bi-Directional Scattering Distribution Function (BSDF) offers shading.
- For all GPUs, Disjoint Orthogonal Triangles Strips (DOTS) offer premium strand-based hair.
Additional RTX Rendering Technologies
Generative AI Face Rendering
A new generative AI technique called RTX Neural Faces enables developers to traverse the uncanny valley in real time. A character dataset created from the model’s original photos is used to train this AI model. Variants with varying lighting circumstances, moods, and occlusion are added to the base character dataset using a synthetic generation technique. After that, this model creates an improved face in real time using a rasterized face and a 3D position.
Better With DLSS and Reflex
AI is used by the ground-breaking DLSS suite of neural rendering technologies to increase frame rate, lower latency, and enhance image quality. With the help of fifth-generation Tensor Cores and NVIDIA GeForce RTX 50 Series GPUs, the most recent innovation, DLSS 4, offers improved Ray Reconstruction and Super Resolution together with revolutionary Multi Frame Generation.
In competitive games, reflex technologies improve aim precision, target acquisition, and reaction times by optimizing the graphics pipeline for maximum responsiveness. Frame Warp, a feature of Reflex 2, further lowers latency by using the most recent mouse input from the game.
Improving Ray Traced Shader Performance
A speed optimization called Shader Execution Reordering (SER) opens the door to improved memory coherence and execution in ray tracing shaders. By making it simple for programs to rearrange threads on the GPU, SER lessens the divergence effects that arise in particularly difficult ray tracing tasks, such as route tracing. In comparison to GeForce RTX 40 Series GPUs, new SER advancements in GeForce RTX 50 Series GPUs further increase the accuracy and efficiency of shader reordering operations.
