Why does the YMTC Zhitai TiPro9000 2TB cause frame generation jitter and reduced responsiveness in large-scale battles in Warhammer 40,000: Space Marine 2?

In the chaotic middle of a large battle, the game felt sluggish and frame times spiked. I tried lowering texture quality, but the visual degradation was unacceptable. I used GamePP Resource Scheduler to enable memory prefetch and switched the power plan to High Performance. GamePP Hardware Sensors showed bus temperature stabilized below 65℃, and frame generation times converged to 12-15ms with smooth load curves.
