How do I fix SLC cache overflow stuttering in Silksong on GW3500?

Navigating the open world in Hollow Knight: Silksong felt broken; the Great Wall GW3500 512GB SLC cache overflow caused severe stuttering. I tried increasing virtual memory, which worsened the read latency. I then used GamePP NVMe Queue Depth Config to increase the queue depth from 512 to 1024 and enabled forced write cache flush. CrystalDiskMark confirmed 4K random read improved from 35-42MB/s to 55-62MB/s. HWiNFO showed stable temperatures at 40-48℃. This solution saved my gaming experience from constant interruptions.
