How do I fix the significant turn lag and black screens in Sid Meier's Civilization VII on Intel 660P?

I hated the 30ms frame generation lag during era transitions in Civ VII. I tried increasing the page file, but CPU usage spiked to 88-95%, making the game unresponsive. I used GamePP Resource Scheduler to set process priority to Real-time and switched to Balanced power plan. GamePP Hardware Sensors showed SSD temps dropping from 65℃ to 54℃. Frame intervals stabilized at 10ms per GamePP Benchmark. This configuration finally fixed my performance issues.
