How do I stop the stuttering when loading city maps in DEAD OR ALIVE 6?

I was annoyed by the stuttering when loading city maps in DEAD OR ALIVE 6 Last Round. I tried increasing virtual memory, which caused disk conflicts and dropped my frame rate to 30 FPS. GamePP indicated my Samsung 990 PRO with Heatsink (2TB) SLC cache was overflowing. I used GamePP NVMe Queue Depth Config to increase queue depth from 1024 to 2048 and enabled forced write cache refresh. CrystalDiskMark confirmed 4K random read speeds improved from 45MB/s to 68MB/s, and the stutter is gone.
