Any chance Microsoft is listening and working on this? The holiday code freeze is over, folks :)
I recently upgraded my motherboard to a much better model (the new Asus TUF Gaming X570 Pro Wifi II), one effect is that my 3DMark PCIe score jumped from 22.3 to 27.2 GB/s, a crazy +22%. But the 980 Pro's random write iops are still almost the same, perhaps just a small lift due to the motherboard (159K->163K) but still a fraction of the performance due.
