Microsoft's DirectStorage 1.4 boosts game speeds with Zstandard compression

Microsoft has updated DirectStorage to version 1.4, adding support for the Zstandard compression algorithm. This change aims to speed up game loading and improve real-time asset streaming. The technology could soon become more widespread with the next Xbox console, codenamed Project Helix, set to feature it as standard.

DirectStorage was created to move data faster from storage to a GPU's memory, cutting out delays caused by CPU and RAM bottlenecks. The goal is smoother gameplay in large, detailed worlds by loading assets almost instantly. However, adoption has been slow due to the complexity of implementation.

The latest update introduces Zstandard (zstd) as a new compression option. This algorithm promises better performance than the older Deflate standard used in earlier versions. Tests suggest zstd delivers faster decompression, which could reduce load times and improve streaming efficiency. Microsoft is working with GPU makers to optimise zstd support across different hardware. AMD, Intel, Nvidia, and Qualcomm are preparing driver updates to enhance GPU-based decompression. This collaboration should help developers make the most of the new feature. So far, no games have publicly used DirectStorage 1.4 with zstd compression since its preview release on 12 March 2026. Earlier versions, like the one in *Ratchet & Clank: Rift Apart*, sometimes caused frame rate drops due to GPU resource demands. The new update aims to address such issues while offering better compression and faster performance.

DirectStorage 1.4 with Zstandard compression is currently in development and not yet widely used. The technology's inclusion in Project Helix may push it into mainstream gaming. If successful, it could lead to quicker load times and smoother gameplay in future titles.
