Why does Khazan drop to 48 FPS during combat?

Combat in Khazan stuttered at 48 FPS due to NVMe bottlenecks. I tried increasing virtual memory, but it caused disk conflicts. I used the GamePP NVMe Queue Depth Configuration to raise depth to 2048 and set High Performance mode. CrystalDiskMark confirmed 4K random reads hit 68-75MB/s, and AIDA64 showed stable 42-55℃ temps. This verify step ensures smooth combat.
