DirectX Raytracing Gets Clustered Geometry for Higher FPS and Up to 90 Percent VRAM Savings

Posted on
DirectX clustered geometry aims to improve raytracing efficiency, increase FPS, and cut VRAM use by up to 90 percent in some scenes.

Quick Report

Microsoft is expanding DirectX raytracing with clustered geometry, a technique that improves efficiency in complex scenes while lowering the memory burden on graphics hardware. In real-world terms, the idea is to help games render more detailed effects without burning through VRAM at the same rate.

The size of the VRAM savings is striking, with the technology reportedly cutting memory use by up to 90 percent in some workloads. That matters because modern raytracing can quickly become a bottleneck on GPUs, and improvements in scene structure can lead to both better performance and more efficient use of available memory.
