l’occasion de la GDC 2025 Microsoft a dtaill les avances de son API DirectX Raytracing 1.2. Le gant prcise que cela est d de nombreuses collaborations avec des gants du secteur, tels qu’AMD, Intel, NVIDIA et Qualcomm…
DXR 1.2 introduces two revolutionary technologies: opacity micromaps (OMM) and shader execution reordering (SER), both of which deliver substantial leaps in raytracing performance:
- – Opacity micromaps significantly optimize alpha-tested geometry, delivering up to 2.3x performance improvement in path-traced games. By efficiently managing opacity data, OMM reduces shader invocations and greatly enhances rendering efficiency without compromising visual quality.
- – Shader execution reordering offers a major leap forward in rendering performance up to 2x faster in some scenarios by intelligently grouping shader execution to enhance GPU efficiency, reduce divergence, and boost frame rates, making raytraced titles smoother and more immersive than ever. This feature paves the way for more path-traced games in the future.
Microsoft mise donc sur l’optimisation de la gomtrie et des shaders afin d’obtenir des gains substantielles en Ray Tracing et Path Tracing.
With help on stage from our partners at Intel, AMD, and NVIDIA, we highlighted key use cases for the technology:
- –
Neural Block Texture Compression is a new graphics technique that dramatically reduces memory usage, while maintaining exceptional visual fidelity. Overall, our partners at Intel shared that by leveraging cooperative vectors to power advanced neural compression models, they saw a 10x speed up in inference performance.
- – Real-time path tracing can be enhanced by neural supersampling and denoising, combining two of the most cutting-edge graphics innovations to provide realistic visuals at practical performance levels.
- – NVIDIA unveiled that their Neural Shading SDK will support DirectX and utilize cooperative vectors, providing developers with tools to easily integrate neural rendering techniques, significantly improving visual realism without sacrificing performance.
Microsoft mise sur l’importance grandissante des rseaux neuronaux, afin de favoriser la compression des textures et rduire la consommation de VRAM. Tout en ouvrant la porte au rendu neuronal mis en avant rcemment par NVIDIA.
