Why does DEATHLOOP stutter during dimension shifts on Kioxia G2?

The irregular frame drops in DEATHLOOP were nerve-wracking, especially when the screen froze for 0.6s mid-fight. I tried increasing the system virtual memory page file, which stopped some crashes, but 45-65ms random read latency via CrystalDiskMark persisted. It was infuriating. Using GamePP NVMe Queue Depth Configuration, I realized high depth caused write amplification. I tried dropping depth to 4, but loading became glacial. I eventually settled on a depth of 32 with write merging. RTSS showed frame times stabilized at 16-24ms, temps stayed 35-42℃ per HWMonitor, and fans hit 1200-1500RPM via GamePP. Perfect set
