How to fix Zhitai TiPro9000 cache overflow in Witcher Remake?
The thrill of teleporting across the map is finally back! After optimizing the write cache policy, the random read performance of the Zhitai TiPro9000 4TB got a massive boost, cutting load times from 12 seconds down to just 4. I wasted way too much time trying to 'defrag' the drive at first, which is just stupid for an NVMe and actually adds unnecessary wear. Total rookie mistake. I eventually installed the latest NVMe controller drivers and enabled 'Force Write Cache Flushing' in the Windows performance settings, while disabling PCIe Link State Power Management. CrystalDiskMark showed 4K random reads jumping from 52MB/s to 78-85MB/s, and those micro-stutters during scene transitions are gone. I did have a weird lag during shutdown right after enabling the cache, but a quick tweak to the power plan sorted it out. The drive runs between 42-55℃ with the heatsink. The in-game performance tool confirms the read mode switch worked perfectly, keeping temps stable at 42-55℃.
