Forspoken Loads In Two Seconds On PC When Using DirectStorage

gamespot.com:

Microsoft recently released its DirectStorage API to game developers, giving them access to the same technology that has made Quick Resume one of the best features on the Xbox Series X|S consoles. Theoretically, DirectStorage promises lightning-fast speed for loading a PC game, and in practice, it looks like it could be a massive upgrade on that platform.

As spotted by PC Gamer, footage of upcoming RPG Forspoken showed the game being loaded in an astonishing 1.9 seconds from an M.2 SSD. Using a SATA SSD, that time increased to a still-impressive 3.7 seconds, and on a regular SATA SSD the game was ready to play in 21.5 seconds. The scenes used to show off these speeds were made up of around 20,000 files weighing in at 4.5GB in total, with the DirectStorage API boasting a file IO speed of 4,839MB/s against the Win32 API on the same drive which was clocked at 2,826MB/s.

There is a caveat to this though, as the technology isn't exactly plug-and-play software. Developer Luminous Productions had to optimize it for Forspoken, and the studio did note that improvements could be made to prevent data bottlenecks with graphics decompression. Microsoft is working on fine-tuning the technology and refining it in the future.

As for how it works, DirectStorage allows the GPU to communicate directly with an SSD so that games and textures can be loaded without needing to check in first with the CPU and main memory. This potentially allows for near-instantaneous loading of a game,
