Thank you for your reply. I would like to clarify some points:
Regarding BypassIO, it was indeed the primary focus of my initial post. It's crucial to understand that BypassIO is currently operational on any Windows 11 system equipped with an M.2 SSD. This high-performance I/O path is not exclusive to DirectStorage; it also serves as a foundation for other technologies, such as I/O Rings.
As for DirectStorage, I concur with your observation. Currently, only Forspoken supports DirectStorage, with Diablo 4 expected to follow suit later this year. I apologize if my previous post gave a different impression; my intention was to provide accurate information, hence the inclusion of relevant articles.
DirectStorage, which is built upon BypassIO, is designed to enhance game performance by facilitating direct loading of assets from an NVMe SSD to the GPU, bypassing the CPU. This is particularly beneficial for games featuring expansive open-world environments that require streaming of substantial graphical assets.
The adoption of new technologies in the gaming industry often follows a pattern of initial limited implementation, followed by rapid expansion as the benefits become more evident and the technology enters the mainstream. This pattern is evident in the adoption of technologies such as DLSS/FSR or ray tracing, which, despite initial limited support, are now increasingly prevalent.
It's also worth noting that the underlying technology empowering DirectStorage is not confined to the PC platform. Both the PlayStation 5 and Xbox Series X have implemented similar concepts with their custom SSD solutions that facilitate rapid asset streaming. The significant investment by both major console manufacturers in this technology underscores its importance for the future of gaming, and we can anticipate future PC ports of games designed to benefit from these storage architectures.
In the realm of PC gaming, Nvidia's RTX IO serves as a prime example of this trend. RTX IO, designed to work in tandem with Microsoft's DirectStorage API, facilitates rapid GPU-based loading and game asset decompression. This mechanism allows developers to load assets directly into the GPU memory, bypassing the CPU and reducing the strain on the system's storage subsystem.
While the current number of games utilizing DirectStorage may be small, the potential impact of these technologies on the future of gaming is substantial. Still, today, just having BypassIO support would be very welcome.
