Why do I get fragmented movement in Stellar Blade combat scenes?

Every time I used a special move in combat, a noticeable stutter occurred, making the action feel broken and disjointed. I tried disabling C-States in the BIOS, which helped slightly but pushed idle temperatures to 50℃—a superficial fix that left me feeling defeated. I used the GamePP Fan Curve Configuration to set a four-stage speed jump (60-70-85-100) and switched to the High Performance power plan. The GamePP FPS tool confirmed 1% lows rose from 22 to 38 fps, with AIDA64 showing temperatures stable at 72-78℃ and core voltage at 1.22-1.31V per GamePP.
