DirectStorage GPU Decompression, RTX IO, Smart Access Storage

It should be NVMe > PCIe > GPU > VRAM shown in red

There is no "NVMe > PCIe > GPU" route. That feature didn't make it into Windows 11 yet. It's in any case "NVMe > PCIe > RAM > PCIe > VRAM". Just the used APIs (Overlapped + Copy via compute shader / IORing + Copy via Copy Engine) differ with "DirectStorage" Off / On. GDeflate is merely yet another compute shader chained - and will also be naturally stalled by the copy on the wrong engine in the "non-DirectStorage" path.

But yeah, the way it's drawn is pretty much garbage.

Had they drawn the red arrows, I'd have understood that.
