Microsoft Shader Execution Reordering: Up to 90% Ray Tracing Boost on Intel Arc, 80% on NVIDIA Blackwell

Posted on
Microsoft SER boosts ray tracing on Intel Arc B-Series and NVIDIA Blackwell GPUs, with up to 90% gains in demos.

Quick Report

Microsoft has introduced Shader Execution Reordering (SER) in its latest Agility SDK (v1.619), enabling dynamic ray sorting for highly optimized parallel execution in DirectX 12. Tech demos show up to 90% framerate improvement on Intel Arc B-Series GPUs and 80% on NVIDIA Blackwell GPUs, with 40% gains on RTX 4090.

SER is expected to deliver significant real-world ray tracing performance boosts once implemented in games, though actual gains may be lower than lab results. Supported hardware includes Intel Battlemage discrete GPUs, Panther Lake Xe3 iGPUs, and NVIDIA Blackwell. AMD support is planned for future architectures. Developers can test SER using Microsoft's demo, but widespread adoption will take time as game engines integrate the new technology.
