Well-known complete system benchmarking suite 3DMark is now adding a DirectStorage feature test to its suite of features. This DirectStorage feature test demonstrates the transfer rate of NVMe storage to GPU VRAM (storage-to-scene speed, basically) across three speed tiers: no DirectStorage, DirectStorage, and DirectStorage with GDeflate. Without GDeflate, DirectStorage only increases maximum throughput to about ~5.85 GB/s from 3.38 GB/s— but with GDeflate, that can go as high as 13 GB/s thanks to the magic of file compression.
Essentially, by ensuring your system can adequately perform the steps required to support DirectStorage and GDeflate, your system should be able to pass this 3DMark DirectStorage feature test. You only need an NVMe drive (PCIe 4.0 or newer recommended) and a compatible graphics card. While GDeflate is an open GPU compression standard introduced by Nvidia, nothing is stopping it from running on modern AMD and Intel graphics cards.
