Xbox tech set to reduce CPU overhead by up to 40% when gaming on Windows 11

Windows 11 gamers could get some really beefy benefits from DirectStorage tech, which was recently announced to have arrived on Microsoft’s newest OS – but it’ll be some time yet before developers incorporate it into games.

We already knew that Windows 11 would give users ‘optimal’ results with DirectStorage (compared to Windows 10) in terms of what this feature does – namely seriously speeding up NVMe SSDs.

However, there’s been an eye-opening revelation concerning exactly how much difference this will make when it comes to relieving the pressure on the PC’s processor.

As TweakTown reports, Cooper Partin, a senior software engineer at Microsoft, explained that the DirectStorage implementation for PC is specifically designed for Windows.

Partin noted: “DirectStorage is designed for modern gaming systems. It handles smaller reads more efficiently, and you can batch multiple requests together. When fully integrated with your title, DirectStorage, with an NVMe SSD on Windows 11, reduces the CPU overhead in a game by 20-40%.

“This is attributed to the advancements made in the file IO stack on Windows 11 and the improvements on that platform in general.”

A 40% reduction is a huge difference in terms of lightening the load on the CPU, although that is a best-case scenario – but even 20% is a big step forward for freeing up processor resources.

Those resources can then be used elsewhere to help big open world games run more smoothly – as we’ve seen before, DirectStorage isn’t simply about making games load more quickly. There’s much more to it than that, and now we’re getting some exciting glimpses of exactly how much difference this Microsoft tech could make to PC games.

Of course, while the public SDK (software development kit) has
