How to fix screen tearing during combat in Final Fantasy XV?

The graphics in FFXV are top-tier, but the screen tearing during intense combat and fast turns was unbearable. I tried enabling 'Ultimate Performance' in the Windows power plan, but while the system felt snappier, the I/O bottleneck remained. I used the GamePP Resource Scheduler to raise the game's I/O priority to maximum and restricted background sync software. RTSS showed frame generation time converged from 30-55ms to 18-26ms. HWMonitor recorded temps at 45-52℃, and GamePP monitoring showed disk active time over 90%.
