Microsoft has unveiled its newest Agility SDK for DirectX, marking a significant leap in ray tracing capabilities with features like Shader Execution Reordering (SER) and Opacity Micromaps (OMM).
These developments promise to enhance performance dramatically. SER optimizes GPU thread reordering, cutting divergence and boosting parallelism, potentially doubling performance in path-traced games. Meanwhile, OMM leverages hardware-accelerated alpha testing, trimming unnecessary AnyHit shader invocations, and achieving up to 2.3 times faster performance by smartly managing transparency.
The Agility SDK 1.717-preview introduces Cooperative Vectors, which unlock enhanced hardware acceleration, streamlining neural rendering in real-time graphics. Additionally, updates to Direct3D Video Encoding include advanced HEVC Reference Lists, a two-pass encoding process, and improved Peak Signal to Noise Ratio (PSNR) metrics.
With SDK 1.616-retail, Tiled Resource Tier 4 support allows more flexible texture streaming and mip mapping, removing prior limitations. Major graphics card manufacturers like AMD, Intel, and NVIDIA are either supporting or gearing up to support these advancements, ensuring broad compatibility.
In practical applications, games like Remedy’s Alan Wake, which heavily rely on alpha-tested geometry, show remarkable improvements. For example, NVIDIA demonstrated a scene running at 90 FPS with OMM, compared to 55 FPS without it.
With such impressive performance gains, these technologies are set to revolutionize gaming experiences, allowing developers to fully harness the power of modern GPUs in their upcoming titles.
