Does the Zhitai TiPro9000 4TB cache fill up and cause lag in Splinter Cell Remake? Should I touch pagefile?

Every time I flicked the camera in the shadows, the loading bar would just hang—totally ruins the stealth vibe. Once the SLC dynamic cache on the Zhitai TiPro9000 4TB fills up, write speeds tank from 7000MB/s to under 1200MB/s, which is where that lag comes from. I tried setting the virtual memory to half my free space, but that just made the I/O conflicts worse in this remake, and the stuttering actually increased. I ended up going into Device Manager, bumping the NVMe controller queue depth from 1024 to 2048, and forced the write cache flush in Windows performance options. CrystalDiskMark showed 4K random reads jumping from 50-60MB/s to 75-82MB/s, and scene swaps dropped from 15 seconds to about 6. The system had a weird drive detection delay at first after the queue tweak, but switching to High Performance mode killed that. Drive temps are 45-58℃ with the stock heatsink, and the input response is finally instant.
