Thanks to CTOnews.com netizen OC_Formula for clue delivery! CTOnews.com April 20 news, when Windows 11 is released in 2021, Microsoft together brings heavy technology DirectStorage API to gamers. This new API changed the way games read data from NVMe SSD drives, resulting in faster read speeds and shorter load times, which were later released in Windows 10.

According to Microsoft official website April 18 news, DirectStorage 1.2 API officially released, mainly for mechanical hard disk HDD optimization, CTOnews.com attached updates as follows:

IODirectStorage currently opens files in unbuffered mode, which avoids unnecessary copies and transfers data to the GPU as quickly as possible. However, some game developers feedback that they want to be able to use the same code on both high-speed SSDs and traditional HDDs.

Traditional HDD mechanical hard drives require buffered IO to mask long seek times. To this end, DirectStorage 1.2 adds the ability to configure DirectStorage to open files in buffered mode to optimize the HDD experience through OS file buffering.

The new GetCompression Support API DirectStorage currently selects the decompression path for the built-in compression format based on GPU support capabilities. In some cases, a CPU-based fallback path is chosen. Game developers feedback that they need to know which decompression path is being used so they can set default texture resolution settings based on this. To achieve this, DirectStorage 1.2 adds a new API to query the path selected at runtime.

Bug fix Fixed an issue by adding a "Reserved1" field to DSTORAGE_REQUEST_OPTIONS. This makes the memory layout of the structure more explicit, but does not actually change the layout of previous versions.

Fixed DSTORAGE_REQUEST_DESTINATION_TEXTURE_REGION for 3D textures.

Fixed scheduling issues when transferring uncompressed data from memory to buffer.

Performance boosts Move decompressed copies of GPUs to compute queues on faster GPUs.

In terms of games, there are not many works that support DirectStorage, only Forspoken, which was launched in January, and Diablo 4 will also support DirectStorage.
