How to fix I/O blocking and screen tearing in God of War Ragnarök?

It's ridiculous—a masterpiece, yet during intense combat transitions, the screen tearing pulls me right out of the game. I tried enabling 'Ultimate Performance' in Windows, but while response time improved, the I/O bottleneck remained, which was incredibly frustrating. I used the GamePP Resource Scheduler to set the game's I/O priority to maximum and restricted background disk scanning. RTSS showed frame times converged to 18-26ms, and HWiNFO recorded SSD temps at 45-52℃.
