Fixing Core Voltage Jitter in Need for Speed
High-load computation in Need for Speed (New) caused visible stuttering; my Intel Core i5 12600KF voltage fluctuated between 1.15V and 1.25V per AIDA64, spiking frame gen time to 15ms. I tried locking core frequency, which failed to reduce stutter and dropped my frame rate from 120 to 90 FPS. Using GamePP BIOS Load Line Voltage Wizard, I set Load Line to L3 and adjusted core voltage from 1.20V to 1.25V. AIDA64 confirmed voltage stabilized at 1.22-1.24V, and frame generation time dropped to 8ms. HWiNFO64 showed temps at 75-80℃, so I finally set the right baseline.
