Microsoft's DirectStorage makes NVMe SSD nearly 70% faster than Win32

The DirectStorage API SDK finally came to Windows recently, which means game developers can now start using the technology to implement it in PC games. After that, today we announced at the 2022 Game Developers Conference ( The first demo of a game using DirectStorage was shown at GDC) event.

Luminous Productions’ Forspoken (formerly Project Athia) has acquired this feature, and in impressive numbers. Several loading scenarios were shown in the demo, and the improvements using Microsoft's DirectStorage looked large, even with SATA-based SSDs; the gap was even wider with faster NVMe SSDs.

#During the demo, a chart is also provided showing the I/O (input-output) rate and corresponding game load time when using DirectStorage with the Windows Win32 Storage API.

This gain is especially impressive when you look at NVMe data, as it shows DirectStorage (4,829 MB/s) compared to Win32 (2,862 MB/s) s) increased by nearly 70%. In actual load times, though, the difference isn't that huge, but it could mean some games will load faster in the future.

As you may have noticed in the video above, in addition to Microsoft's DirectStorage, Forspoken is also getting AMD's new FidelityFX Super Resolution (FSR) 2.0, although support for the feature is currently still in development middle. However, implementing it might not be too difficult since the game already uses FSR 1.0 features.
