Why does Manor Lords stutter when my town grows on ONDA H610M?

I felt totally cheated when my beautiful medieval village started lagging; frame rates plummeted from 60 to 25 FPS as the population grew, killing the immersion. I tried enabling power-saving mode in the BIOS to keep things cool, but that was a mistake—it actually worsened the drops and tanked my minimum FPS. I finally used GamePP Resource Scheduler to elevate the game process priority from Normal to Real-time and suppressed three heavy background services. After testing, RTSS confirmed frame times converged to 12-18ms, and HWMonitor showed VRM temps at 54-59℃.
