How to fix screen tearing in Atomic Heart on Jginyue X79 PRO?

In this fast-paced action game, I felt a slight discrepancy between my attacks and the visual feedback, which was infuriating. I tried enabling V-Sync to align frames, but input lag spiked to over 45ms per InputLag tool, making the controls feel like walking through mud. I switched to the GamePP Resource Scheduler, elevating the process to Real-time and pinning rendering threads to physical cores. RTSS showed frame times converging to 14-19ms, and 3DMark confirmed stable fan speeds at 1400-1600 RPM.
