Fixing WD SN850 storage latency in Judgment: Lost Saga
While fast-traveling, I noticed the storage response latency was bouncing between 1.2-2.8ms. It didn't crash the game, but the instability caused these annoying micro-stutters. I tried turning on 'Game Mode' and flushing my RAM, but the FPS just hovered between 50-62 without any real improvement. I eventually went into the disk management tools, switched sector alignment from 'Auto' to manual calibration, and updated the NVMe drivers. The latency immediately flattened to 0.9-1.1ms, and frame time variance dropped from 14.2-20.8ms to 9.5-11.1ms. I actually tried overclocking my CPU to 'force' the data through faster, which just caused local overheating and two system crashes before I realized the storage link was the real bottleneck. The drive gets a bit warm during long sessions, but it's exactly where I want it. CrystalDiskMark confirms the random read latency is now locked at 0.9-1.1ms.
