The Microsoft DXR API was designed years ago, before the level of geometric complexity that can be found in modern games. In DXR, geometry is represented using a Bounding Volume Hierarchy (BVH), which can become expensive to rebuild in dynamic scenes with dense geometry and countless complex animated objects. Fully ray tracing such geometry may require frequent BVH updates, placing significant strains on performance. As a result, developers often rely on lower-quality proxy meshes for ray-traced effects. These simplified representations contain only a fraction of the original detail, leading t
