Microsoft’s latest DirectX Raytracing (DXR) upgrade appears to be delivering on its remarkable performance claims, with independent testing on an AMD Radeon RX 9070 XT revealing massive improvements in acceleration structure efficiency and memory consumption. As we reported last week, Microsoft’s DirectX 12 Agility SDK 1.722 Preview introduces Clustered Geometry, Partitioned Top-Level Acceleration Structures (PTLAS), and GPU-driven acceleration structure builds. Together, these features could enable more efficient ray tracing of highly detailed environments, similar to NVIDIA’s proprietary RTX Mega Geometry technology. Following AMD’s November 3 announcement confirming support for the new features on RDNA 4 GPUs, graphics enthusiast Osvaldo Pinali […]
