Why does the UE5 Matrix Demo stutter during fast camera movements?

I was totally immersed in the Matrix demo until micro-stutters started hitting every time the camera swept across reflections. It was infuriating. I tried cranking the CPU power limit to 250W in the BIOS, but temperatures spiked to 95℃ per AIDA64 and I got a BSOD immediately. To fix this, I used the GamePP Fan Curve Configuration Panel to set a 70℃ trigger for rapid speed increases, capping the max at 1500 RPM. Now, CPU temps stay at 72-78℃ per AIDA64, and frame times dropped from 16-38ms to 11-14ms per RTSS. I finally feel at peace.
