How to fix I/O read latency on Intel 760P 2TB for Minecraft?
Exploring complex terrain with ray tracing enabled often triggers these split-second freezes, which is a classic nightmare for QLC-based drives like the Intel 760P 2TB. After diving into the performance analyzer, I noticed random 4K read latency spiking to 35-50ms, meaning the chunks just couldn't keep up with my movement. I initially tried lowering the render distance in-game, but the stutters persisted, leaving me questioning the controller's scheduling logic. I then headed into Device Manager, switched the disk write caching policy from default to enabled, and pushed the I/O priority to the max via the registry. In subsequent tests, the disk wait time dropped from 40ms to a much tighter 12-18ms, and the world loading became noticeably fluid. I did run into a scare where a sudden power outage caused minor data corruption right after enabling the cache, so I didn't feel safe until I installed a stable PSU. The drive temps stayed between 40-48℃. After exporting the disk policy via a system snapshot, my frame times finally stabilized at 5.1-6.4ms.
