   DirectX Update Could Cut Ray Tracing Memory Usage by Up to 90%

   Microsoft is previewing two DirectX features, Clustered Geometry and Partitioned TLAS, which it calls the most significant update to DXR since its 2018 debut. In Microsoft's own testing on an AMD Radeon RX 9070, ray tracing memory use dropped from 7.5 GB to 774 MB while frame rates rose from 1.2 fps to 79 fps. The update is not yet widely available, and not all games are expected to match those results.

The trend compares the same fully observed sources, so its range can be smaller than the current heat. Move the pointer or click for each hour. Left and right arrow keys move the point.
