How to fix map loading stutters on Zhitai TiPro9000?
When loading the massive city models in Rome, I noticed the progress bar would just freeze randomly, which is a total nightmare for a technical player. While the Zhitai TiPro9000 kills it in sequential reads, the random 4K small file performance was swinging wildly between 45-52MB/s, pushing system I/O wait times up to 120ms. I tried disabling the Windows Indexing service first, but that was a complete waste of time; the stuttering stayed exactly the same. I eventually installed the OEM NVMe drivers and bumped the queue depth from 32 up to 128, while forcing the write-cache buffer flush in Device Manager. After a second pass in CrystalDiskMark, random reads jumped to 68-74MB/s, shaving nearly 4 seconds off the load time. I actually messed up by trying a 64K cluster size at one point, which corrupted some of my saves—I had to format the whole thing to get it back. Temperatures stayed between 42-55℃ with a stable controller load. I verified the read curve was smooth via I/O analysis, and frame times finally settled at 5.1-6.4ms.
