DirectX Integrates Shader Execution Reordering for Performance

Microsoft adds hardware Shader Execution Reordering (SER) to DirectX Raytracing (DXR) 1.2 in the DirectX Agility SDK v1.619, exiting preview today. The SDK also includes Shader Model 6.9 to enable SER and Opacity Micromaps (OMMs); vendor demos report Nvidia GPUs gaining about 40% performance and Intel Arc B-series up to 90% more FPS. Game developers and GPU vendors must adopt these features for player-facing improvements.
