What DirectStorage actually requires
- An NVMe SSD (PCIe Gen4 recommended); SATA and hard drives do not qualify.
- Windows 10 or 11 with current GPU drivers.
- A supported game; unsupported titles simply load at normal NVMe speed.
- No Gen5 needed: a good Gen4 drive gets the full benefit.
How it helps
DirectStorage lets a game stream compressed assets straight to the GPU, which decompresses them. That removes a CPU bottleneck and shortens load times and texture pop-in in supported games. It is the reason a modern NVMe SSD matters as much as your graphics card for a smooth experience.
