How to fix SLC cache lag on Zhitai TiPro9000 1TB SSD?
During the rat swarm sequences, every time the camera shifted, the game would freeze for a split second, which totally killed the immersion. Once the Zhitai TiPro9000 1TB's dynamic SLC cache fills up, random read speeds plummet from 70MB/s to a miserable 20-30MB/s, causing severe I/O blocking. I tried moving the game to a different partition, but the stutters were still there—moving the files doesn't fix a hardware cache limit. I installed the latest NVMe drivers and changed the write cache policy to 'Force Flush' in Device Manager, while killing useless indexing services. CrystalDiskMark showed 4K random reads climbing from 42MB/s to 65-72MB/s, and the map transitions are way smoother. I did experience some drive detection delays initially, which only vanished after switching the power plan to High Performance. Drive temps stay between 45-52℃ with the stock heatsink, and the in-game analyzer confirms I/O latency is finally under control.
