By using the GPU to decompress game content, Microsoft’s DirectStorage technology can certainly improve load times. Could, at least in theory. Consequently, the more data that is then processed via the GPU, the more likely it is that gamers will notice a loss of graphics performance.
The German PC Games Hardware team demonstrated just that and tested the game with three different storage types: PCIe Gen4, PCIe Gen3 and SSDs connected to SATA. Such a memory was connected to an Intel Core i9-12900K system. As the first game to support Microsoft DirectStorage, Forspoken is not only a testing ground for game developers, but for GPU manufacturers. All companies involved now need to consider the performance implications of using this technology, but results will vary depending on the hardware.
The RTX 4090 suffered a loss of up to 10% at 4K resolution from 83.2 to 74.4 average FPS when switching from DirectStorage to SATA to PCIe Gen4 SSD. However, it is important that the slowest frames, the so-called 1% percentile FPS, do not show a big difference, so the gameplay should remain similarly smooth.
However, no details were given on the website about exactly which memory was used. More comprehensive tests that also include other GPUs and different resolutions/quality settings are obviously required to draw conclusions. Furthermore, one would expect a PCIe Gen5 comparison to be included now, especially since such products are already available for other testers(watch the video).
