DIRECTX 12 ULTIMATE

DirectX 12 Ultimate is Microsoft’s latest graphics API, which codifies NVIDIA RTX’s innovative technologies first introduced in 2018, as the cross-platform standard for next-generation, real-time graphics. It offers APIs for Ray Tracing, Variable Rate Shading, Mesh Shading, Sampler Feedback, and more, enabling developers to implement cinema-quality reflections, shadows, and lighting in games and real-time applications. With the DirectX 12 Agility SDK, developers can get the latest ray tracing technologies and graphics API’s immediately on any Windows 10 version November 2019 and newer.

DirectX

Ray Tracing

Real-time ray tracing for realistic reflections, lighting and shadows that take advantage of NVIDIA RTX RT cores.

Mesh Shading

New type of shader that combines vertex and primitive processing, increasing the flexibility and performance of the geometry pipeline.

Variable Rate Shading

Dynamically vary the shading rate for different regions of a frame, which increases rendering performance.

Sampler Feedback

Control how and when textures are loaded to speed up rendering and reduce GPU load.

Ray Tracing

RTX Direct Illumination

Realistic Lighting and Shadows

RTX Direct Illumination (RTXDI) offers realistic lighting of dynamic scenes that require computing shadows from millions of area lights.

RTX Global Illumination

Multi-Bounce Indirect Lighting

RTX Global Illumination (RTXGI) provides scalable solutions to compute multi-bounce indirect lighting without bake times, light leaks, or expensive per-frame costs.

NRD

Denoising Library

NVIDIA Real-Time Denoiser is a spatio-temporal API agnostic denoising library that’s designed to work with low ray per pixel signals.

Latest APIs

Mesh Shading

Flexible Shading Model

Mesh Shading offers a new shader model for the vertex, tessellation, and geometry shading stages of the graphics pipeline, supporting more flexible and efficient approaches for computation of geometry

VRSS

Dynamic Texture Quality

Variable Rate Shading allows developers to control shading rate dynamically, shading as little as once per sixteen pixels or as often as eight times per pixel.
