Tuning Intel Core i5 14600KF power limits for Ghost of Tsushima
This CPU runs like a space heater. Whenever I get into a massive combat encounter, the framerate bounces around like a yo-yo, which is just ridiculous. Out of the box, the PL1 limit is around 125W, causing the clock speeds to swing wildly between 3.5-5.2GHz during heavy physics calculations. I tried enabling 'Ultimate Performance' mode in Windows, but the temps just shot straight to 100℃ and triggered a massive throttle, which felt like a total waste of time. I went into the BIOS, bumped both PL1 and PL2 to 180W, and set a voltage offset of -0.05V. In RTSS, the frame time variance dropped from a messy 16-40ms to a tight 11-15ms. After cranking the power, my AIO fans sounded like a jet engine until I rebuilt the fan curve from scratch. Now the CPU stays between 78-85℃ with clocks holding above 5.1GHz. I exported the stress test logs to confirm, and fan speeds are steady at 1400-1600RPM.
