How to fix loading stutter in Metaphor: ReFantazio on Great Wall GW3500 1TB?

I was frustrated when the SLC cache saturated during Ozma map teleports, causing write speeds to drop from 5000MB/s to 700MB/s. I tried increasing virtual memory, but it only made disk conflicts worse. I then used GamePP NVMe Queue Depth Config to raise the queue from 1024 to 2048. CrystalDiskMark showed 4K random read improved from 45-50MB/s to 65-72MB/s. AIDA64 confirmed disk temp at 40-52℃. Load time dropped from 10s to 4s, saving my gameplay flow. This setting effectively save the performance.
