As a PC gamer, you might need already heard about DirectStorage. Introduced manner again in 2020 by Microsoft, DirectStorage is an API that goals to considerably cut back recreation loading instances, enhance GPU efficiency, and cut back CPU overhead, primarily on Home windows 11. Whereas DirectStorage was publicly launched to builders in March 2022, avid gamers have but to see the expertise ship the transformative advantages Microsoft had promised years in the past.
A lot of the delay within the widespread adoption of DirectStorage is linked to the challenges builders are going through in implementing the expertise and overcoming some undesirable points that it introduces in video games. Though most NVMe SSDs and modern graphics cards already assist DirectStorage, there may be nonetheless a lot to be achieved to completely leverage its potential. Let’s take a look at the 5 major issues it’s worthwhile to know to remain abreast of what is taking place with DirectStorage on Home windows 11.

How precisely does DirectStorage work?
What goes on beneath the hood?
The traditional manner of streaming recreation property works by loading compressed property from the storage to the RAM, at which level they’re decompressed by the CPU, after which moved from the RAM to the GPU VRAM. What DirectStorage does, in a nutshell, is enable video games to make the most of the excessive bandwidth of NVMe SSDs and allow the GPU to take over the decompression step, accelerating your complete pipeline and shifting the majority of the load from the CPU to the GPU.
The CPU is not eradicated from the pipeline, opposite to what most individuals assume. It nonetheless handles the IO requests, however not like the older manner of doing issues, the CPU is helped by high-speed NVMe {hardware}, which is why the largest advantages of DirectStorage are seen on NVMe SSDs, and never SATA SSDs or hard drives (sure, DirectStorage is now supported on them too).
GPU decompression wasn’t at all times a characteristic of DirectStorage, however was launched in DirectStorage 1.1 in November 2022. With DirectStorage 1.2 in April 2023, Microsoft additionally launched a buffered IO mode which primarily hurries up information switch from slower drives resembling HDDs as nicely, bringing them into the fold. Along with lowering recreation load instances as property spend much less time residing within the storage and are decompressed a lot sooner, DirectStorage additionally improves GPU efficiency by providing the additional bandwidth of the SSD to be used by the GPU.

State of DirectStorage in 2024
The story so far
There is no debate that DirectStorage has been lower than a success, at the very least up to now. Whereas a handful of video games have applied the expertise and proven promising outcomes — Forspoken, Horizon Forbidden West, Forza Motorsport, and extra — the sport trade has largely been unable to undertake the expertise to a big extent.
The challenges behind it aren’t fully unknown both. The PC port of Ratchet & Clank: Rift Aside shipped with DirectStorage assist, however was discovered to run smoother with out it (when some avid gamers deleted the related recordsdata and observed the enhancements). Sport builders have been going through difficulties exhibiting common advantages of DirectStorage throughout video games, with it being largely situational. They’ve additionally confronted struggles migrating to the newer DirectStorage API and programming video games round it.
Whereas it is a foregone conclusion that increasingly video games will ship with DirectStorage assist in 2025 and past, it is secure to imagine that the expertise is not going to remodel video games anytime quickly, particularly for these already rocking high-speed NVMe SSDs and powerful gaming GPUs.

What do you want for DirectStorage?
The {hardware} necessities aren’t that steep
So, what sort of {hardware} do it’s worthwhile to make the most of DirectStorage when it lastly turns into extra widespread in video games? Whereas Microsoft recommends Home windows 11 for the perfect outcomes, Home windows 10 can also be supported, albeit with decreased performance. In addition to the OS model, you additionally want at the very least a PCIe 3.0 NVMe SSD and a GPU with DirectX 12 assist. The necessities are summarized beneath on your reference:
- Home windows 10 model 1909 or later
- NVMe SSD (PCIe 3.0 or sooner) for finest outcomes (though SATA SSDs and HDDs are additionally supported)
- GPU with assist for DirectX 12 and Shader Mannequin 6.0
Regardless of many individuals already having graphics playing cards with assist for DirectStorage, they most likely will not be capable of see nice ends in the close to future. In keeping with Nixxes, the developer behind the PC ports of Ratchet & Clank: Rift Aside and the Horizon video games, when engaged on the port of Forbidden West, “the GPU decompression API is just too restrictive as to how one can combine and match decompression codecs, and GPU decompression may cause scheduling points within the driver we won’t account for.”
For this reason Horizon Forbidden West, regardless of utilizing DirectStorage, would not use GPU decompression and nonetheless depends on the CPU for a similar. Next-generation graphics cards would possibly characteristic a {hardware} decompression block just like that current on consoles to enhance the decompression facet of issues. With the problems surrounding GPU decompression resolved in time, we’d be capable of see DirectStorage ship the outcomes avid gamers have needed to see for therefore lengthy.

Hold Home windows and GPU drivers up to date
Do not miss out on DirectStorage enhancements
The newest main launch (DirectStorage 1.2) is nearly two years outdated now, however Microsoft is probably going engaged on bringing refinements with up to date variations, if not one other main launch. Preserving your Home windows 11 system up to date will mechanically offer you entry to the newest DirectStorage model, obtainable for use by any recreation that helps it.
In addition to Home windows, additionally it is really useful to keep your GPU drivers updated, particularly when a brand new model accompanies a brand new recreation launch. If the builders handle to implement DirectStorage within the recreation, updating your GPU driver will seemingly provide the finest efficiency. As Microsoft releases new variations of DirectStorage, GPU producers resembling Nvidia, AMD, and Intel can even launch drivers to assist them.
These of you with older GPUs missing DirectX 12 assist won’t be able to leverage DirectStorage, nevertheless, and will take into account upgrading down the road if you wish to expertise the expertise.
