AMD DGF SuperCompression cuts geometry storage size by up to 22%
Key Points:
- AMD has released DGF SDK 1.2, introducing DGF SuperCompression (DGFS) to reduce the storage size of Dense Geometry Format (DGF) assets used for dense mesh compression.
- DGFS acts as a smaller storage format that can exactly reconstruct original DGF blocks and decode to standard vertex and index buffers, enabling compatibility with non-DGF hardware.
- Testing shows DGFS reduces asset sizes by roughly 30% compared to raw DGF data, with further size reductions of around 20% when combined with GDeflate compression.
- Decode times on a Ryzen 9 7950X system demonstrate efficient performance, with DGFS decoding faster than DGF blocks and potential support for GPU-based decoding on RDNA4 and later architectures.
- While similar in addressing dense geometry for ray tracing, AMD’s DGF focuses on compression and is not directly compatible with NVIDIA’s RTX Mega Geometry, which targets acceleration structure building.
