Why does Expeditions: Rome freeze when zooming out the map?

I felt totally robbed of immersion while deploying Roman legions; zooming out to the full map caused maddening micro-stutters, with GamePP sensors showing read latency fluctuating between 12-28ms. I tried closing all unnecessary background services in the system, but loading times only decreased by less than a second, failing to address the I/O bottleneck. I then used the GamePP NVMe Queue Depth Configuration to increase the queue depth from 1024 to 2048 and forced the high-speed write refresh strategy. CrystalDiskMark confirmed random read speeds rose to 78-84MB/s, and AIDA64 monitoring showed the drive temperature stabilized at 42-50℃. It's finally smooth!
