4090 takes a hit on DirectStorage implementation, doesn't seem too significant but definitely registers.
DirectStorage 1.1 moves game asset decompression from the processor to the graphics card. Microsoft's demo showed that scenes load almost 3X faster on a graphics card than the processor. Of course, your mileage will vary and depend hugely on your hardware. Nevertheless, it's an exciting technology that will make loading screens a thing of the past. While many news outlets are focusing on benchmarking the impact of DirectStorage on loading times, PC Games Hardware took it a step further and measured the effect that Microsoft's technology has on frame rates.
Forspoken, from Square Enix, is the first game to leverage DirectStorage, the foundation for PC Games Hardware's tests. The publication's system consisted of a Core i9-12900K (Alder Lake) processor and a GeForce RTX 4090, one of the best graphics cards, at 4K. The reviewer tested with a SATA SSD and two M.2 SSD but didn't mention the exact models."
DirectStorage Causes 10% Performance Hit On RTX 4090 In Forspoken
"Microsoft's DirectStorage technology has brought lightning-fast loading times to games. However, it would seem that not everything is sunshine and rainbows. DirectStorage may induce a slight performance loss, according to the latest test by the German publication PC Games Hardware (opens in new tab).DirectStorage 1.1 moves game asset decompression from the processor to the graphics card.
