Phantom Blade Zero is lagging during big fights because the Zhitai TiPro9000 1TB cache is full, should I change write policies?

The combat in this game is an absolute blast, and when the loading is fast, the immersion is just peak. However, once the Zhitai TiPro9000 1TB's SLC dynamic cache fills up, write speeds crash from 7000MB/s to under 1000MB/s, causing 15-25ms of loading lag. I tried switching the power plan to 'Balanced', but that just tanked my read speeds to 4000MB/s—obviously a bad move for a high-performance SSD. Instead, I went into Device Manager, bumped the NVMe queue depth from 1024 to 2048, and forced the write cache flush policy. CrystalDiskMark showed random 4K reads jumping from 50MB/s to 70-80MB/s. I had a brief moment where the drive wasn't detected after the tweak, but switching to 'High Performance' power mode killed that bug. Temps are stable at 45-58℃ with the heatsink. Storage analysis confirms the speeds are back, and the cache mode is finally switched.
