I'm getting instant freezes and massive read latency in Delta Force during big battle loads. Why?

This drive was pushing me to my limit when handling massive map assets; every load felt like a slideshow. Once the Zhitai TiPro9000's SLC cache maxes out, the write speed craters from 7000MB/s to under 900MB/s, leaving the system in a brutal I/O wait for 0.6-1.1 seconds. I tried moving the game to a RAM disk, but it just ate all my memory and gave me a Blue Screen of Death—that was a total disaster. I eventually went into Device Manager, increased the NVMe controller queue depth from 1024 to 2048, and enabled the forced write cache flush. CrystalDiskMark showed 4K random reads moving from 45-52MB/s to 68-75MB/s, and the stuttering dropped by about 40%. I did get a file corruption error the first time I tweaked the queue, but disabling my real-time antivirus fixed it. Temps are stable at 48-55℃, and fan speeds are holding at 1400-1600RPM.
