This is attributed to the advancements made in the file IO stack on Windows 11, and the improvements on that platform in general." When fully integrated with your title, DirectStorage with an NVMe SSD on Windows 11 reduces the CPU overhead in a game by 20 to 40%. "It handles smaller reads really efficiently, and you can batch things together to get more work done. "DirectStorage is designed for modern gaming systems," says senior engineer at Microsoft, Cooper Partin. The idea is that with DirectStorage all that happens simultaneously. DirectStorage is designed to streamline the process of taking that compressed game data off a drive and then rendering it. Part of DirectStorage is about using the speed of the SSD memory and the interface it's built on to reduce the CPU overhead that occurs when shifting game data around system memory, decompressing it, and then sticking it into the GPU's frame buffer. ![]() Limited because hard drives were still a thing in some gaming PCs and all consoles. ![]() Up to now we've still been somewhat limited to the lowest common denominator: the slow hard drive.Īs much as we've had new PCIe drives and the introduction of the NVMe protocol, which massively changed how responsive an OS installed on it was and also how fast games could load, there were still limiting factors at play. Why should you care about DirectStorage?īut first, what is DirectStorage and why should you be interested in the first place? Basically, now that the two main consoles are both using solid state drive technology, there's an appetite for actually using the performance of SSDs to their fullest. Anyways, I've tested a bunch of drives, from the best PCIe 4.0 SSD, down to SATA and external SSDs, then all the way down to a wee 2.5-inch 7,200RPM hard drive I found at the back of the PC Gamer kit cupboard with some of Alan's old 'files' on them.
