DirectX Raytracing 1.2: Game-Changing Performance Boosts

• 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.

NVIDIA was already doing these in a few games, but nice to have them as part of the standard

Cooperative Vectors & Neural Rendering: Next-Generation Realism

• 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.
