WD Black SN850 2TB read latency backup for Horizon
After roaming the wilds for four hours, the instant loads started turning into 2-3 second white screens. It's absolutely maddening. Monitoring showed the WD Black SN850 2TB random read latency creeping up from 0.04ms to 0.11-0.17ms in GamePP—classic cache fragmentation. I tried the built-in Windows defrag, but doing that to an SSD is just wrong and adds unnecessary wear; what a joke of a suggestion. I enabled the GamePP Resource Scheduler Panel to auto-flush the NVMe cache every two hours and locked the game I/O priority to maximum. On the sensor page, the latency curve stopped climbing and became a stable wave, with FPS holding at 72-80 on RTSS. The first auto-flush caused a tiny 0.
