DirectStorage simplifies the task of asynchronous queuing, dispatch, and notification of I/O requests and transfer. Asynchronous executionĪsynchronous I/O can be difficult to implement correctly with traditional storage APIs, and most software relies on serialized I/O. DirectStorage encourages batching multiple requests simultaneously with a simplified API to maximize throughput.

Traditional serialized file I/O is no longer aligned with modern gaming and just-in-time rendering. Modern storage devices, such as NVMe ® are optimized for multiple simultaneous workloads to maintain peak throughput. With it, developers have the capability to significantly reduce load times on PC.ĭirectStorage offers the following features to improve I/O performance in games: We believe that DirectStorage has the potential to change PC gaming. It simplifies the process of batching file read requests, asynchronous transfer of resources to the GPU or CPU, and prioritization of that I/O on its way to its destination. The DirectStorage API encourages developers to write more optimal code for both Windows 11 and Windows 10.
