Hopefully this will get wide support

Would like to know real config for uncompressed "blu line"? PCIe3.0?

I think that is CPU to GPU copy using unpinned buffers. We've measured that bandwidth for using unpinned buffers for our CUDA code. If you want to achieve the full PCI-E bandwidth you have to transfer the data via pinned buffers. For CUDA at least, when you use unpinned buffers it will copy the data from the unpinned buffers to a pinned buffer and then copy across the PCI-E bus, which is why the achieved bandwidth is so much lower (due to the extra copy and certain limitations in the Intel processors, at least before Alder Lake). I'm assuming that they used a similar setup with DirectX here.

would be nice to see benchmarks against XPRESS4K and XPRESS8K compressed data.

Ah, okay , thanks for info. I am not a CUDA pro, but assume it has to do with CUDA driver APIs new function calls, cause as far as I know, kernel allocated CPU memory is or was restricted if pinned.

finally PC gets the "magic ssd" of PS5 😛 😀 joking but good news anyway can't wait to see it in games like forza horizon or open worlds which I guess ?! would benefit the most

This is crazy. There is a tool available here you can see it working: [youtube=uWSOw2-PGEo] From 2.7ish GBs to 8.7. The implications of that are mind blowing.

I bet it will take as long as DirectX 12 for DirectStorage to be used by game developers.

Hdds can reach 400 mb sequencial reads with out raid ????

on old slower HDD yuo can speed up already a lot resource loading using windows 10 xpress compressions.
