Why does my Intel 660P 2TB slow down during the landing phase in Apex Legends?

Landing in Apex Legends was painful as my Intel 660P 2TB SLC cache overflowed, dropping write speeds below 800MB/s. I tried increasing virtual memory, but it caused more read/write conflicts. I used GamePP NVMe Queue Depth Configuration to set depth to 2048 with forced flush. CrystalDiskMark showed 4K random reads at 68-75MB/s. Load time cut from 12s to 5s. This set prevents frame drops during critical gameplay moments.
