How to reduce input lag in Far Cry 7 with Intel Core i5 12600KF?

I was in a jungle ambush when my character's firing lagged behind my mouse clicks, creating a fatal delay that made me lose the fight. I tried adjusting process priority via Windows Task Manager, but background interference caused frame rates to drop to 42 FPS, making the issue worse. I then used GamePP Resource Scheduler to lock the game process to real-time priority and restrict background threads. According to GamePP Hardware Sensor, CPU core utilization stabilized from 55-72% to 82-88%. GamePP Frame Time Analyzer confirmed that frame generation time dropped from 14ms to 9ms, and 1% Low FPS increased to 58, ensuring a smooth combat flow.
