How to stop screen tearing in MGS V on the Galax H410M Shadow?

While attempting stealth in the Definitive Edition, rapid camera movements caused distracting screen tearing. I tried increasing virtual memory to 32GB, but this didn't reduce the 92-115ns latency per AIDA64 and actually dropped my FPS from 60 to 52 per MSI Afterburner. I used the GamePP Resource Scheduler to raise the process priority to Real-time and manually locked memory timings to 2666MHz per CPU-Z in BIOS. Frame generation time finally converged to 13-17ms per RTSS, with memory temperatures stable at 40-46℃ per HWMonitor.
