How do I reduce loading stutters in Cities: Skylines II combat scenes?

Scene switches caused severe stutters as VRAM write speed dropped. I tried increasing virtual memory, but it made things worse. I was frustrated. I used GamePP NVMe Queue Depth Config to raise depth from 1024 to 2048 and enabled forced write cache. CrystalDiskMark showed 4K reads improved to 68-75MB/s. It helped me backup my stable config.
