Release of Agility SDK 1.722 as the biggest ray tracing update since 2018
Microsoft has released the preview version of the “DirectX 12 Agility SDK 1.722”. This release adds “clustered geometry”, “high-level fragmented acceleration structures”, and direct GPU-driven acceleration structure building operations, which the company describes as the most important ray tracing update in DirectX since its debut in 2018.
These features were rolled out on October 28, 2026, alongside the stable commercial release version 1.620, and aim to reduce the computational cost of keeping ray tracing data up to date in detailed and constantly changing gaming worlds. They do not require new hardware beyond current ray tracing-capable gear, though card manufacturers must provide supporting drivers.
Mechanism of clustered geometry, fragmented acceleration structures, and benchmark results
Before a GPU can trace light rays, it needs acceleration structures that organize scene geometry, and these structures must be rebuilt whenever characters move or new objects stream in, according to Tweaktown. The “clustered geometry” feature groups objects into reusable sets containing up to 256 triangles and 256 vertices, allowing game engines to reuse them as the level of detail changes instead of rebuilding from scratch, according to Jon Peddie Research.
At the same time, the “fragmented acceleration structures” feature retains unchanged parts of the scene and updates only the moving sections, while indirect build operations allow inputs to be supplied from GPU memory rather than the central processor.
Microsoft’s test sample on an AMD Radeon RX 9070 graphics card jumped from 1.2 frames per second using traditional methods to 79 frames per second with “clustered geometry”—about 66 times faster. Build time also dropped from 788 milliseconds to 3.11 milliseconds, and memory consumption fell from 7,519 MiB to 774 MiB according to Wccftech, noting that these figures belong to a single test sample and full commercial games are not expected to run 66 times faster.
Support for GPUs from Nvidia, AMD, Intel, and Qualcomm
The new preview works on all Nvidia RTX GPUs, the AMD Radeon RX 9000 series, Intel Arc B-Series cards, Core Ultra 200V and Series 3 processors, with support planned for Qualcomm Snapdragon X2 processors in the first half of 2027.
Nvidia says the new API unifies its technology known as “RTX Mega Geometry”, and it has enabled the features via driver version 621.01, while Microsoft pointed to “Gears of War: E-Day” as an early example of this approach.
Adoption of Shader Model 6.10 and commercial release roadmap
The new ray tracing features rely on “Shader Model 6.10”, which is still in preview and scheduled for commercial release with the Agility SDK 1.621 package in early December, while the final commercial release date for the ray tracing features themselves has not yet been set.
In a comprehensive analytical reading, standardizing clustered geometry and fragmented acceleration structures across various GPU manufacturers represents a fundamental step to ease the work of game developers and enable them to deliver dynamic worlds rich in lighting and physical details.
In addition to these technical details, reports from Windows Central, Tweaktown, Wccftech, and Jon Peddie Research highlight the broad industry integration behind the release of the DirectX 12 Agility 1.722 preview. Support for Nvidia RTX processors via “Mega Geometry”, AMD Radeon RX 9000 cards, Intel Arc and Core Ultra processors, and upcoming Qualcomm Snapdragon X2 processors in 2027 gives game developers a unified standard for accelerating ray tracing and reducing memory consumption.
As part of the comprehensive editorial review for the Friday, October 30, 2026 bulletin covering the “game ray tracing update” file, journalistic verification based on primary sources and documented news reports emphasizes the necessary methodological distinction between officially announced financial and technical figures and future expectations or preliminary tests under evaluation, ensuring Arab readers receive integrated and accurate coverage spanning all aspects of the event and its direct and indirect ramifications on the global AI sector and future competition among major tech companies.
