MGSV Definitive Edition is stuttering during scene transitions on my Great Wall GW3300 256GB. Why?

Whenever I entered a stealth base, the screen would micro-freeze every few seconds, which is incredibly stressful when you're trying to stay hidden. Because the Great Wall GW3300 256GB is so small, the SLC cache completely dies once occupancy hits 85%, causing write speeds to plummet from 2000MB/s to around 400MB/s. I first tried disabling all indexing services in Windows, but that only shaved off 0.2 seconds of lag—a total waste of time. I eventually cleared 60GB of junk to keep the free space above 35% and manually triggered the TRIM command to force flash block recovery. CrystalDiskMark showed sequential writes climbing back to 1600-1800MB/s, and the stuttering totally vanished. I did notice CPU usage spike to 40% for about five minutes after the first TRIM run, but it settled down. The SSD now runs between 38-46℃ with a load fluctuation of 60-75%. The performance panel confirms the resource scheduling is back to normal, and the storage settings are finally dialed in.
