How to fix Intel 660P write drops in AC Valhalla?
Exploring England is great until you feel those micro-stutters every few minutes; it makes combat feel unresponsive and dangerous. Resource Monitor showed the Intel 660P's QLC NAND was bottoming out after the SLC cache filled up, with writes dropping from 1000MB/s to about 150MB/s, causing 200ms response peaks. I tried cleaning temporary files first, which freed 10GB but did nothing for the lag—just a band-aid solution. I then manually triggered a full-drive TRIM and tweaked the disk write cache flush frequency in the registry. In LatencyMon, the disk-induced DPC latency dropped from 1.5ms to 0.4ms, and the lag vanished. I actually had a scare where the drive disappeared for 5 minutes after the TRIM, but a reboot fixed it. Temps are 38-45℃ with average response times at 15-22ms. I/O tests confirm the response is back to normal, and it's staying cool at 38-45℃.
