How to fix late-game lag in Civilization VII on Jginyue B760M?

In the late stages of global management, every turn switch caused an extremely unsmooth tearing sensation, making operations feel sluggish and anxiety-inducing. I first tried increasing virtual memory to 64GB; while loading speed improved slightly, the frame time fluctuations remained severe, proving this was a scheduling bottleneck. I enabled the GamePP Resource Scheduler, forced the game process to Realtime priority, and cut background services. Frame time converged to 12-18ms per RTSS, with CPU temps at 70-78℃ per HWMonitor and RAM at 45-52℃ per AIDA64.
