Microsoft teased the arrival of its DirectStorage 1.1 API virtually a month in the past, and it’s now obtainable (opens in new tab) for builders to get began with its newly applied GPU decompression performance. Bear in mind, Direct Storage 1.1’s headlining capability is accelerating recreation load occasions by as a lot as 40%, relying upon the sport and PC {hardware} configuration.
In a weblog publish heralding the arrival of DirectStorage 1.1, Microsoft wrote largely to the viewers of builders, pointing to guides, assets, and describing what’s new from a technical viewpoint. The important thing affirmation is that “GPU decompression and GDeflate [are] now obtainable.” However there are a selection of efficiency will increase and bug fixes to Direct Storage basically, too.
The utility worth of DirectStorage going ahead will depend upon quite a lot of issues. On the buyer aspect, PC players will want trendy {hardware} to really feel any advantages, with no less than a DirectX 12 + Shader Mannequin 6.0 GPU, plus a quick, trendy storage system like one of many newest NVMe SSDs.
Within the demos showcased final month, Microsoft shared a screenshot the place DirectStorage 1.1 was utilized in a reasonably superb setup, and it loaded a ‘recreation’ scene as much as 3X sooner than an earlier API. Furthermore, the GPU-powered decompression decreased CPU masses considerably. However, after all, whether or not your CPU or GPU has extra ‘spare time’ will rely so much on the sport engine and your {hardware}.
Importantly for the adoption of this information loading acceleration API, some optimized drivers are already prepared. Microsoft linked to assist pages from key PC {hardware} companions like AMD, Intel, and Nvidia (opens in new tab) in its weblog. When you comply with the respective hyperlinks, you possibly can be taught extra about every vendor’s work to assist DirectStorage 1.1.
AMD highlights the essential proven fact that “DirectStorage is a characteristic that should be enabled by (recreation) software builders to appreciate the advantages.” Thus, finish customers can’t simply await a brand new GPU driver. Sadly, AMD hasn’t confirmed whether or not it has already applied DirenctStorage 1.1 assist in a delivery driver or whether it is one thing we’ve to stay up for.
Nvidia says that the present Sport Prepared Driver (model 526.47) consists of optimizations for GDeflate. It supplied some efficiency comparability charts exhibiting the clear benefits supplied by GPU decompression in recreation / degree loading.
Intel says its Arc graphics driver 101.3793 consists of DirectStorage 1.1 optimizations for Intel Xe structure on programs with NVMe SSDs. It additionally kindly shared some efficiency examples. In its instance that includes a system utilizing an Intel Core i9-12900K CPU and Arc A770 16GB GPU, the decompression bandwidth was elevated from 7.88 GB/s to 21.67 GB/s.

So, recreation builders can, ultimately, start in earnest implementing DirectStorage 1.1, with the carrot on the finish of the stick being considerably shorter loading occasions and sooner recreation information streaming. We stay up for seeing the enhancements to obtainable video games coming as patches, in addition to new video games coming with DirectStorage 1.1 enabled from launch.
