How to fix screen stuttering while moving fast in Final Fantasy XV?

I was so excited to speed through the streets of Insomnia, but the experience was marred by maddening micro-stutters. I first tried manually setting priorities in the Task Manager, but the game crashed immediately, proving that such a crude intervention wouldn't work. I then used the GamePP Resource Scheduler to set the game to Realtime priority and bound computation tasks evenly across all physical cores. RTSS showed frame times converged from 15-42ms to 10-13ms, and AIDA64 confirmed CPU temps at 72-78℃.
