Why are resources loading slowly in Nightingale with a WD SN770 SSD?

While building complex magical structures, I found resource loading became abnormally slow, with models appearing with a delay. I first tried reinstalling the NVMe controller driver in Device Manager, but loading speed only improved by 2%, which was clearly insufficient. I used the GamePP Peripheral Driver Conflict Detection tool to find a third-party backup service competing for I/O and set it to manual. CrystalDiskMark showed random reads stabilized at 65-72MB/s, with drive temperature at 38-46℃ per CrystalDiskInfo.
