For the previous 12 months we have been listening to about how Microsoft’s DirectStorage API will supercharge PC gaming with sooner load instances, and facilitate “virtual worlds that are more expansive and detailed than ever,” to make use of Microsoft’s personal phrases. It holds a number of promise, however does your PC assist the characteristic? There’s now a simple strategy to examine.
More on that in a second, however let’s take a high-level overview of DirectStorage and what it might imply for gaming.

What Is DirectStorage And Why Does It Matter For Gaming

Storage through the years has elevated in velocity fairly a bit, because of the appearance of strong state drives (SSDs) and the continued evolution in each NAND flash reminiscence and controller chip applied sciences. Today’s quickest SSDs push reads and writes north of seven,000 MB/s, and upcoming PCI Express 5.0 fashions will go twice as quick (finally).
The downside is that the velocity positive aspects will not be felt throughout the board, and never in gaming. That’s to say, you would be laborious pressed to inform a distinction between a PC working a 2.5-inch SATA SSD rated to ship 560 MB/s of sequential efficiency, versus one outfitted with an M.2 NVMe SSD that may ship 7,000 MB/s or extra.
This is a generalization, after all, as random 4K learn and write IOPS matter for sure duties, and never everybody makes use of their PC in the identical means. But if strictly speaking about gaming, video games will run and reply just about the identical between these two SSDs, regardless of an enormous velocity benefit of the NVMe mannequin.

Enter the PlayStation 5 and Xbox Series X|S. Sony and Microsoft lastly made the swap to SSD storage, and instantly builders have much more incentive to faucet into these velocity positive aspects. And to assist them, each have made I/O facet tweaks. On the Xbox Series X|S, this is named Microsoft’s Velocity Architecture, and the DirectStorage API brings the identical know-how over to PC.
As Microsoft factors out, gaming workloads have developed. In the outdated days, video games would load giant chunks of knowledge into shared accessible system and GPU reminiscence, leading to a smaller variety of I/O requests. But these days, video games break textures and different property into smaller chunks and cargo solely those wanted to render a selected scene. It’s a extra environment friendly means of doing issues, on the expense bumping up the variety of I/O requests in comparison with the outdated methods.
“Unfortunately, current storage APIs were not optimized for this high number of I/O requests, preventing them from scaling up to these higher NVMe bandwidths creating bottlenecks that limit what games can do. Even with super-fast PC hardware and an NVMe drive, games using the existing APIs will be unable to fully saturate the I/O pipeline leaving precious bandwidth on the table,” Microsoft explains.
DirectStorage addresses this shortcoming in a number of methods, resembling decreasing per-request NVMe overhead, enabling batched many-at-a-time parallel I/O requests that may be fed to the GPU, and giving video games higher management over being notified when an I/O request has been accomplished.

Microsoft Releases A Tool To Check If Your PC Supports DirectStorage

One of the necessities for DirectStorage is an NVMe SSD, and ideally a PCIe 4.0 mannequin. You additionally want a DirectX 12 GPU with Shader Model 6.0 assist (something fashionable, actually). Microsoft additionally recommends Windows 11, which it says has all of the “latest storage optimizations built in,” but it surely’s supposed to have the ability to work in Windows 10 as effectively.
As noticed by PC Gamer, If you wish to examine the standing of your PC, there’s a simple means to do this, it is only a matter of going via a number of steps.
  1. Head to the Microsoft Store and download the Xbox Insider Hub app.
  2. Click on Previews on the left-hand facet, then choose Windows Gaming (you might have to scroll down).
  3. Click on Join to turn into an Xbox Insider (this step is critical)
  4. Go again to the Microsoft Store, click on on Home (if not already there) then click on on Library within the left-hand facet.
  5. Click the Get Updates button. This ought to set up the Xbox Game Bar.
  6. Once put in, kind Xbox Game Bar within the Windows Search or press Windows Key + G to load the Xbox Game Bar.
  7. Click the Settings icon, then click on on Gaming Features.
Interestingly, on our Windows 10 system, it says “Needs upgrade” subsequent to the OS. But the 2TB Samsung 980 Pro SSD in our system makes the minimize with an “Optimized” designation, the GPU (GeForce RTX 3090 Ti) is listed as “Supported.”
Microsoft has not mentioned an entire lot about Windows 10 and DirectStorage, solely that they are appropriate. But it is going to be attention-grabbing to see if, as time goes on, the “Needs upgrade” message goes away.
