DirectX Integrates Shader Execution Reordering for Performance
8.4
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.
Key Points
- 1Standardizes shader execution reordering (SER) in DXR 1.2 via DirectX Agility SDK v1.619
- 2Delivers substantial frame-rate gains—Nvidia ~40% and Intel Arc B-series up to ~90% in demos
- 3Enables GPU vendors and game developers to adopt hardware SER and Shader Model 6.9 for optimization
Scoring Rationale
Strong official SDK standardization with demonstrable FPS gains, limited by developer adoption and hardware implementation timelines.
