How to fix combat stutter in Metaphor: ReFantazio?

I felt frustration when summoning units in Metaphor: ReFantazio caused momentary stutters due to SLC cache overflow. I tried setting virtual memory to half the disk space, but it worsened disk read/write conflicts and increased frame drops. Then, I used GamePP NVMe Queue Depth Config to set queue depth to 2048 and enabled forced write cache refresh. CrystalDiskMark showed 4K random read speed improved to 68-75MB/s, and HWiNFO verified NVMe temperature at 42-55°C.
