How to fix resource scheduling lag on Intel 660P 2TB?
Whenever I'm sprinting through those open machine habitats, the game just hitches for about half a second, which completely kills the immersion. The issue is that the QLC NAND on the Intel 660P 2TB tanks hard once the cache is exhausted, with random read speeds plummeting from 300 MB/s to a pathetic 80 MB/s, meaning the assets can't load fast enough for the engine. I first tried disabling every single background update service in Windows, but that only shaved off maybe 0.2s of lag—a total waste of time. I eventually used a partition tool to recalibrate the 4K alignment and forced the write-cache buffer flush in the driver settings. After that, my CrystalDiskMark 4K random read latency tightened up from 62ms to a much healthier 35-15ms range, and the frame drops vanished. Oddly, my boot time increased by about 2s after the partition tweak, but switching the power plan to High Performance sorted that right out. Temps are sitting between 42-55℃ with minimal fluctuation. I locked this config in the motherboard manager, and now my frame times are rock steady at 5.1-6.4ms.
