As PC gaming enthusiasts continue to explore the potential of DirectStorage, a technology introduced by Microsoft in 2020, many are left pondering its true impact on gaming performance. This API, designed to enhance loading times and optimize GPU efficiency, has been available to developers since March 2022, yet gamers are still waiting for the promised benefits to materialize.
The slow adoption of DirectStorage can largely be attributed to the hurdles developers face in integrating this technology into their games. While most modern NVMe SSDs and graphics cards support DirectStorage, realizing its full potential remains a work in progress. Here are five essential insights to keep you informed about the current state of DirectStorage on Windows 11.
How exactly does DirectStorage work?
Traditionally, game assets are streamed from storage to RAM, where they are decompressed by the CPU before being transferred to the GPU’s VRAM. DirectStorage revolutionizes this process by allowing games to utilize the high bandwidth of NVMe SSDs, enabling the GPU to handle decompression. This shift not only accelerates the entire pipeline but also alleviates some of the CPU’s workload.
It’s important to note that the CPU still plays a role in managing IO requests, but with the support of high-speed NVMe hardware, the most significant advantages of DirectStorage are observed on NVMe SSDs rather than SATA SSDs or traditional hard drives. The introduction of GPU decompression in DirectStorage 1.1 and buffered IO mode in DirectStorage 1.2 has further enhanced the technology, allowing for faster data transfers even from slower drives.
State of DirectStorage in 2024
Despite its promise, DirectStorage has not yet made a significant impact on the gaming landscape. A few titles, such as Forspoken and Horizon Forbidden West, have showcased its capabilities, but the broader industry has struggled with widespread implementation. Developers have encountered challenges in demonstrating consistent benefits across various games, leading to mixed results.
For instance, the PC version of Ratchet & Clank: Rift Apart included DirectStorage support but performed better when players removed the associated files. As the gaming community anticipates more titles with DirectStorage support in the coming years, it remains clear that the technology will not drastically transform gaming experiences in the immediate future.
What do you need for DirectStorage?
To take advantage of DirectStorage, users need specific hardware, although the requirements are not overly demanding. Microsoft recommends Windows 11 for optimal performance, but Windows 10 is also compatible, albeit with limited functionality. The essential requirements include:
- Windows 10 version 1909 or later
- NVMe SSD (PCIe 3.0 or faster) for best results (SATA SSDs and HDDs are also supported)
- GPU with support for DirectX 12 and Shader Model 6.0
While many gamers possess compatible graphics cards, the benefits of DirectStorage may not be immediately evident. Developers have noted that the GPU decompression API can be restrictive, leading to scheduling issues that hinder performance. As next-generation graphics cards emerge, the hope is that they will include hardware decompression capabilities, allowing DirectStorage to fulfill its potential.
Keep Windows and GPU drivers updated
With the latest major release of DirectStorage nearing two years old, Microsoft is likely working on updates to refine the technology. Keeping your Windows 11 system up to date ensures access to the latest DirectStorage versions, which can be utilized by any compatible game.
Additionally, updating GPU drivers is crucial, especially when new versions coincide with game releases. As developers implement DirectStorage, updated drivers from manufacturers like Nvidia, AMD, and Intel will enhance performance. However, users with older GPUs lacking DirectX 12 support may need to consider an upgrade to fully experience DirectStorage’s benefits.
DirectStorage on Windows 10
For those still using Windows 10, the operating system remains a solid choice, with support continuing until October 2025. While DirectStorage is supported on Windows 10, the most significant advantages will be seen on Windows 11. As more games adopt DirectStorage and graphics cards improve their decompression capabilities, users will be better positioned to decide whether to upgrade or remain with Windows 10.
In the meantime, the future of DirectStorage looks promising. With advancements in hardware and software, gamers may soon enjoy the transformative experiences that this technology was designed to deliver.
