How to fix slow texture loading on Zhitai TiPro9000 1TB?
It was honestly immersion-breaking to see rough stone walls stay blurry until I was practically touching them. I discovered that once the SLC cache on the Zhitai TiPro9000 1TB gets fragmented after long sessions, the random 4K read performance tanks from 75MB/s down to a pathetic 32-41MB/s, causing the engine to choke on texture requests. My first instinct was to run the built-in Windows disk defragger, which was a total mistake—it didn't help at all and actually added about 15ms to the system response time. I realized the issue was at the driver level, so I flashed the latest official firmware and disabled the NVMe controller's power management mode. In CrystalDiskMark, the random reads stabilized at 68-74MB/s, and town loading times dropped from 18 seconds to a snappy 9 seconds. I did have a brief scare where the drive disappeared from the system right after the update, but a quick reseat of the M.2 slot and cleaning the contacts fixed it. Temps stayed between 48-55℃. The drive is finally behaving itself.
