How to fix Zhitai TiPro9000 cache stuttering in KCD II?
Whenever I rode through the forests, the game would just freeze for half a second. It was incredibly anxiety-inducing. The issue is that once the Zhitai TiPro9000's dynamic SLC cache fills up, the write speed craters from 7000MB/s to under 900MB/s, causing resource loading to spike. I tried setting the virtual memory to half of my free disk space, but in a massive RPG like this, it actually made the R/W conflicts worse and increased the stuttering. I ended up going into Device Manager and bumping the NVMe controller queue depth from 32 to 64, and disabled unnecessary indexing services in Windows. In CrystalDiskMark, my random 4K reads jumped from 48-55MB/s to 72-80MB/s, which significantly smoothed out the hitches. I did notice a weird disk detection lag during idle after the change, but switching the power plan to 'High Performance' killed that. Disk temps are now 45-55℃, and the loading feels snappy again.
