The Ray Tracing Revolution: Microsoft’s Shader Model 6.9 Unlocks a 90% Power Surge for Intel and NVIDIA

Microsoft announced the formal integration of Shader Execution Reordering (SER) into Shader Model 6.9 (DXR 1.2), describing how SER reorders ray-tracing work on the GPU to improve shader coherence and reduce thread idling. The announcement claims up to a 90% performance gain for Intel Arc B-series and a 40% gain for NVIDIA RTX 4090, and states users will only need driver updates to benefit; this is a graphics/API performance and standards update rather than a cybersecurity report.
