Why does Death Stranding 2 stutter during terrain changes?

Trekking across the desolate wasteland, every time I enter a new region, the screen freezes momentarily, breaking the flow of the journey. I initially tried enabling overclocking mode in the driver, but the core temperature spiked to 92℃ and triggered throttling, which felt ironic and out of control. I used the GamePP Power Plan Switcher to set the mode to High Performance and locked the core frequency at 2700MHz. 1% lows improved from 45 to 68 FPS per RivaTuner, core temperature stabilized at 66-72℃ per HWMonitor, and frequency stayed 2700MHz stable per GPU-Z.
