Microsoft adds Shader Execution Reordering (SER) in latest DirectX SDK for more efficient ray tracing — Intel Arc B-series GPUs show 90% performance uplift

Microsoft has integrated Shader Execution Reordering (SER) into the latest DirectX SDK, enhancing ray tracing efficiency. This feature, now part of DXR 1.2, optimizes per-pixel rendering in ray-traced scenes, improving GPU performance by categorizing reflections and light bounces for better parallel execution. Intel Arc B-series GPUs have shown up to a 90% performance increase with this update. The SDK also includes Opacity Micromaps (OMMs) to save processing power by skipping unnecessary shader work on transparent surfaces. Additionally, Shader Model 6.9 enables developers to utilize these features, potentially leading to performance enhancements in games.

The Nvidia GeForce3 launched 25 years ago — underappreciated at launch, its impact shaped the industry

The Nvidia GeForce3, launched 25 years ago, was initially underappreciated but had a significant impact on the tech industry. It was the first GPU with DirectX 8.0 pixel and vertex shader support, allowing graphics programmers to write programs that run on the GPU. Despite mixed reviews at launch, it paved the way for future advancements in graphics processors. The GeForce3 Ti500, launched later in 2001, introduced the "Ti" appellation and improved performance. Its legacy influenced subsequent GPU developments, leading to advancements like DirectX 9.0c and Shader model 3.0. The GeForce 3's programmability set the stage for NVIDIA's dominance in AI computing today.
