The two new features of DXR 1.2 are Opacity micromaps and Shader execution reordering
Opacity micromaps aim to significantly optimize alpha-tested geometry. According to MS, they can deliver 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.
On the other hand, Shader Execution Reordering offers a major leap forward in rendering performance. This can make DXR be up to 2x faster in some scenarios than its previous version. SER achieves this by intelligently grouping shader execution to enhance GPU efficiency, and reducing divergence. The result is higher frame rates, something that will make raytraced titles smoother and more immersive than ever.
