how does the feature improve game load time?

Microsoft’s DirectStorage 1.1 is out this week and should dramatically reduce game load times. DirectStorage was released earlier this year to minimize CPU overhead, but did not include the feature to help run games on modern PCs. However, the company added the long-awaited feature with the latest DirectStorage 1.1.

What is GPU decompression and how does it work?

In a blog post dated October 13, 2022, Microsoft mentioned that it is in the final stages of development and will release the developer’s unpack by the end of 2022. Additionally, the company claims that this is one of its most requested features. . But what is GPU decompression, anyway?

Computer games require large amounts of data to create immersive and interactive worlds. Each video game landscape, object, and character has certain “assets” that describe its characteristics, such as shape, lighting, and color.

Together, all assets add up to hundreds of gigabytes of data, which are compressed to reduce the overall size of a game. When players start a game, these data-containing resources are transferred to system memory, where the processor decompresses and copies data to the GPU, CPU decompression. This decompression and data transfer results in long loading times.

While DirectStorage 1.0 improved the data transfer aspect of the process, DirectStorage 1.1 moved asset decompression directly to the GPU, eliminating the step where the CPU processes the data and then copies it to the GPU. This method of moving asset decompression to the GPU is called GPU decompression.

DirectStorage 1.1 will improve the Windows gaming experience

Typically, graphics cards are more efficient at performing repetitive tasks, and combined with the bandwidth of a high-speed NVMe drive, GPU decompression on DirectStorage 1.1 reduces the time it takes to load an in-game asset, improving overall gameplay. Microsoft has shown that scenes can load almost three times faster with GPU decompression than with CPU decompression.
