Displacement maps and procedural displacement shaders are a widely used approach of specifying geometric detail and increasing the visual complexity of a scene. While it is relatively straightforward to handle displacement shaders in pipeline based rendering systems such as the Reyes-architecture, it is much harder to efficiently integrate displacement-mapped surfaces in …

Abstract. Displacement mapping is a powerful mechanism for adding fine to medium geometric details over a 3D surface using a 2D map encoding them. While GPU rasterization supports it through the hardware tessellation unit, ray tracing surface meshes textured with high quality displacement requires a significant amount of memory.
RayTracing + Displacement/Tesselation - GameDev
https://www.gamedev.net/forums/topic/702623-raytracing-displacementtesselation/
Adam Miles. DXR doesn't "work with" those types of shaders, but what it does support is refitting and rebuilding of the BLAS that contains the geometry you want to ray trace. If you want to use tessellation to re-tessellate a mesh/model on a continual basis then you'll need to stream the geometry out to a buffer and issue a refit or rebuild of ...
