How to fix loading delays with WD SN850 1TB in RDR2?
The visual fidelity is finally insane without the stuttering. After updating to the latest official firmware and re-calibrating the 4K alignment, the random read speeds on my WD SN850 1TB jumped from a pathetic 800MB/s back up to a peak range of 6200-6800MB/s. At first, I was obsessed with increasing the virtual memory to ease the load, but that actually made things worse by creating disk I/O conflicts, which just increased the stutter frequency—a total waste of time that left me feeling pretty defeated. I eventually went into Disk Management, manually assigned the page file to a separate partition, and bumped the NVMe controller queue depth to 2048. In CrystalDiskMark, 4K random read latency dropped from 60ms to a tight 35-42ms, and scene transitions became fluid. I did notice a brief recognition delay during boot after the firmware update, but switching the power plan from Balanced to High Performance killed that issue. Temps are now steady between 48-55℃. Six consecutive scan cycles confirmed zero errors, and memory temps held at 58-63℃.
