Introducing AMD DGF SuperCompression

AMD has released DGF SuperCompression (DGFS) as part of the AMD DGF SDK v1.2 update. DGFS is a software compression layer on top of the Dense Geometry Format (DGF) that reduces storage size by up to 22% compared to raw DGF blocks, and roughly 20% when both are GDeflate-compressed. Unlike raw DGF blocks, DGFS is not directly consumable by hardware but can be decoded to either DGF blocks or conventional vertex/index buffers (meshlets), enabling a single asset format to target both DGF and non-DGF devices. The system uses cluster-granular compression with techniques including vertex de-duplication, delta encoding, zig-zag encoding, and byte interleaving. Decode performance on a single CPU core is fast enough for streaming scenarios, and a GPU-based decoder is also viable.
