Microsoft debuts DirectStorage 1.4 at GDC 2026, with Zstandard compression and GACL — update promises developers improved compression ratios, faster loading, and more

Microsoft unveiled DirectStorage 1.4 at GDC 2026, featuring Zstandard compression and the Game Asset Conditioning Library (GACL) to enhance compression ratios and loading speed for developers. Zstandard, a compression algorithm from Meta (formerly Facebook), is integrated for efficient data compression and decompression. DirectStorage 1.4 supports Zstd-compressed assets on both CPU and GPU paths, allowing flexibility for developers. The update also introduces global D3D12 CreatorID support to optimize GPU workload scheduling. Despite initial challenges, DirectStorage continues to evolve, offering potential benefits for future game titles with improved compression efficiency and asset streaming capabilities.
