Should I change write cache policies for Zhitai TiPro9000 4TB when read latency spikes in Phantom Blade Zero?

Whenever a fancy combat cinematic kicked in, the loading speed would just tank, and the inconsistency was killing the vibe. Once the SLC dynamic cache on the Zhitai TiPro9000 4TB fills up, sequential reads plummet from 7000MB/s to under 1200MB/s, causing obvious texture pop-in. I first tried setting the virtual memory to half of the remaining disk space, but that just created more I/O conflicts in this action game, and the stutters actually got worse—which was actually exciting because it pointed me to the real problem. I went into Device Manager, bumped the NVMe controller queue depth from 1024 to 2048, and enabled the forced write cache flush policy in system performance options. CrystalDiskMark showed 4K random reads jumping from 50MB/s to 72-78MB/s, and scene transitions got 4 seconds faster. I had some weird drive detection delays at first, but switching the power plan to High Performance cleared it up. SSD temps are between 45-58℃. Cache scheduling is now officially switched.
