Fixing Zhitai TiPro9000 cache overflow in Ghostwire Tokyo
Sprinting through Shibuya looked smooth, but every few seconds there was this tiny, annoying twitch in the movement. I checked the logs and found that when the Zhitai TiPro9000's dynamic SLC cache fills up during high-frequency asset loading, the random read speed crashes from 7000MB/s to 1500MB/s, creating a 18-32ms command delay. I tried enabling Windows Game Mode, but that just prioritized the CPU—the drive was still the bottleneck. I updated the NVMe controller drivers and enabled the 'Force Write Cache Flush' policy in Windows performance options. AIDA64 random read tests now show a stable 62-75MB/s for 4K reads, and the hitching is gone. I had a brief issue where the drive took forever to be recognized at boot after the update, but switching to the High Performance power plan sorted it. Temps are between 48-55℃ and the motherboard is at 52-58℃. Frame times are now locked at 14-18ms.
