Why does Assassin's Creed Shadows stutter during scene transitions?

Every scene transition in Assassin's Creed Shadows caused severe screen tearing, with frame intervals fluctuating wildly from 8-22ms per RTSS. I tried reseating the Asgard Hel DDR5 5600 32GB RAM sticks, but the system black-screened and rebooted, leaving me frustrated and anxious. I then used GamePP Resource Scheduler to set the game process priority to real-time and calibrate the memory channel bandwidth. This action stabilized the dual-channel handshake immediately.
