Why does the i5-14600KF stutter in Kingdom Come Deliverance 2?

Entering Rattay was a total disaster; my frame times jumped from 16ms to a chunky 45-60ms. Looking at the telemetry, the E-Cores were trying to handle physics collisions and stealing resources from the main thread, leaving the P-Cores idling. I tried the 'Ultimate Performance' power plan, but that just cranked up my idle power draw without fixing the stutters—totally useless. I went into the BIOS and capped the E-Cores at 3.2GHz while locking the P-Cores at a steady 5.3GHz. HWInfo showed Vcore sitting between 1.22-1.28V with temps at 62-71℃. I actually suffered a hard reboot during the first boot because the voltage was too low, so I had to add a +0.05V offset to Vcore to stabilize it. Now the load curve is a perfect staircase and compute latency is under 12ms. Cinebench confirms memory temps are chilling at 58-63℃.
