AMD demonstrated new ray tracing technology that can reduce VRAM requirements by up to 47 times using tetrahedral cages. It's no secret that current ray tracing technology not only burdens GPUs with heavy computation, but can also deplete VRAM capacity when games have to handle environments with complex geometry, such as forests and urban areas. AMD is now demonstrating a new approach with tetrahedral cages, which can reduce memory requirements …
AMD Tetrahedral Cages Cut BVH Memory 80 GB to 1.7 GB in Research Demo
By Indie Kings | September 23, 2026 Updated September 23, 2026: AMD GPUOpen research cuts BVH memory in one demonstration from up to 80 GB to about 1.7 GB and update time from more than 300 ms to roughly 3.3 ms, per AMD Fellow Holger Gruen on September 17. The demo ray traces about 500 million animated triangles above 60 FPS at 1080p on Radeon RX 9070 XT. This is research, not a shipping-game result. Contents Why BVH updates matter How tetrahe…
With this ingenious new process, AMD has reduced ray tracing memory usage by 98% for scenes with dense vegetation. With the help of tetrahedral cages, we can get much more beautiful and smoother forest environments in video games in the future.
The red firm presents a tetrahedral cage technique allowing to make animated environments with a drastically reduced memory load. The AMD article unveils a new method to reduce the consumption of VRAM in ray tracing appeared first on Overclocking.com.
Up to 90 percent less memory and only 3.3 ms for BVH updates: AMD's tetrahedron impact presented in the raytracing paper could dramatically accelerate the display of fine, mobile geometry.
News from HD Tecnología. Visit www.hd-tecnologia.com for the latest news. AMD presented a new technique of rendering based on tetrahedric meshes that seeks to drastically reduce the cost of memory and processing of Ray Tracing in complex scenes. The proposal is specially designed for environments with huge amounts of animated geometry, such as vegetation, crowds or distant characters. In a demonstration, the company used some [...] The AMD entry…
