Why does Death Stranding 2 micro-stutter during aiming?

During fast flick-shots, the once-smooth visuals began to micro-stutter, which is completely unacceptable in a competitive setting. I first tried lowering the game's graphics settings; while FPS went up, the micro-stutters remained, making the compromise feel pointless. I enabled the GamePP Resource Scheduler to force the game process to Realtime priority and optimized the memory page file. RTSS showed the frame generation interval stabilized from 12-30ms down to 8-12ms, and AIDA64 recorded CPU temps at 68-74℃.
