Why is there input lag during stealth in The Last of Us Part I?

Approaching enemies in stealth felt risky due to slight judgment delays, which were fatal in the tense atmosphere. I tried increasing virtual memory first, but the judgment delay worsened, a counterproductive and frustrating attempt. I then used GamePP BIOS Load Line Voltage Wizard to lower memory timing to aggressive settings and fine-tune the voltage. After relaxing parameters following an initial blue screen, the system stabilized. GamePP Stress Test confirmed the elimination of judgment delays, with memory latency dropping from 85-95ns to stable levels.
