Microsoft's latest DirectX Agility SDK introduces two key ray tracing upgrades: Shader Execution Reordering (SER) optimizes shader thread scheduling for faster rendering, while Opacity Micromaps (OMM) accelerates alpha-tested geometry handling. These features deliver major performance gains in ray tracing, particularly on NVIDIA RTX hardware, reducing bottlenecks in complex scenes. The update highlights Microsoft's push for real-time ray tracing advancements, giving developers more tools to enhance visuals without sacrificing framerates.
