DRSN is a JSON-based format used to describe render states. A DRSN file is composed of three primary sections:
- Shaders: Defines shader stages, source files, entry points, and macros.
- ResourceSignatures: Contains descriptions of pipeline resource signatures (e.g., constant buffers, samplers).
- Pipelines: Describes pipeline states (PSOs), including graphics/compute settings and links to shaders and signatures.
Important: All shader, signature, and pipeline resource names within an archive must be unique.
