Does the Zhitai TiPro9000 SLC cache failure cause frame drops during map swaps in Kai no Kiseki?

Whenever I fast-traveled through the city, the screen would just hitch every few seconds, and the unpredictability was driving me crazy. The Zhitai TiPro9000 4TB is huge, but when the SLC cache overflows during heavy concurrent reads, the speed tanks from 7000MB/s to about 1200MB/s. I tried increasing virtual memory to 64GB, but that was a mistake—it didn't stop the stutters and actually added 5 seconds to my boot time. I eventually installed the latest NVMe controller drivers and switched the Windows write caching policy to 'Force Flush'. In CrystalDiskMark 4K random read tests, latency tightened from 68-85ms down to 38-45ms. I almost bricked my save file when I tried disabling the write cache entirely, but after re-enabling and tweaking the queue depth, it locked in. Drive temps stayed between 45-58℃ with the heatsink. The loading curves are finally flat, and the game feels snappy under my fingertips.
