Why does my FPS drop to 48 when flying through dense clouds in Dragon's Dogma 2?

Flying through dense clouds caused the CPU to stutter as E-Cores maxed out while P-Cores sat idle, dropping FPS to 48. I tried changing the Windows power plan to High Performance, which helped P-Cores but didn't fix the E-Core scheduling issue. Using GamePP BIOS Load Line Voltage Adjustment Wizard, I set the Load Line to L3 and tweaked VCCSA to 1.25V. Cinebench R23 showed a score increase to 37200, and RTSS confirmed stable frame rates between 95-110 FPS.
