Ray Tracing Optimization with DirectX 12 Ultimate

Microsoft has added Shader Execution Reordering (SER) technology to its latest DirectX SDK, with the aim of improving ray tracing efficiency. This implementation, an integral part of DirectX 12 Ultimate, promises to reduce bottlenecks and increase performance in applications that make intensive use of ray tracing.

Performance Increase on Intel Arc GPUs

Initial results obtained with Intel Arc B-series GPUs indicate a significant performance increase, quantifiable up to 90%. This data suggests that SER technology can have a significant impact on the gaming experience and professional applications that leverage ray tracing.

Implications for Developers

The introduction of SER in DirectX 12 Ultimate offers developers new tools to optimize their applications. By correctly implementing this technology, it is possible to achieve a significant improvement in performance without having to resort to radical changes to the existing code.
