Why does Civ VII freeze for 10 seconds during turn settlement?

In the late game with hundreds of units, every turn settlement froze my system for 10 seconds, which was maddening. I tried enabling memory acceleration in BIOS, but it caused a BSOD immediately upon entering the game, leading to intense anger. I then used the GamePP Resource Scheduler to set priority to Real-time and manually fixed virtual memory to 24GB on my NVMe drive. Turn settlement time reduced to 4s per System Log and FPS stabilized at 30-45 per RTSS with temps at 45-52℃ per HWMonitor.
