Why does my game stutter during combat scene switches on the Zhitai Ti600 500GB?

Combat in Horizon Zero Dawn was unplayable due to random stutters whenever I switched views. I suspected the SLC cache was filling up too fast. I tried setting virtual memory to half my remaining disk space, which only made the read/write conflicts worse and caused more frame drops. I needed a proper storage fix. I used the GamePP NVMe Queue Depth Config to increase the queue depth from 1024 to 2048 and enabled forced write cache refresh. CrystalDiskMark showed 4K random reads jumping from 45-52MB/s to 68-75MB/s.
