Shader Model 6.5 requires explicit architectural support from the GPU manufacturer. The following GPU lineages natively support SM 6.5 features:
Shader Model 6.5 provides enhanced support for DirectX Raytracing 1.1, improving ray tracing efficiency and performance.
: A new, more powerful pipeline to replace the traditional Vertex/Geometry Shader pipeline. Mesh Shaders ( ms_6_5 ) and Amplification Shaders ( as_6_5 ) give developers more control over geometry processing for highly detailed scenes.
