My i5-14600KF keeps jumping clock speeds during heavy fights in S.T.A.L.K.E.R. 2. Any fix for this?

The screen tearing became absolutely unbearable while trekking through the ruins of Chernobyl. The lack of fluidity comes from the i5-14600KF aggressively jumping between 3.8GHz - 5.3GHz while crunching complex AI logic. I first tried slapping the system into 'Ultimate Performance' mode, but while the average FPS went up by maybe 4 frames, the 1% lows were still stuck above 45ms—a total band-aid solution that left me feeling pretty disappointed. I rebooted into the BIOS, swapped the Load Line Calibration from Auto to L2 mode, and manually locked the Vcore at 1.28V. Monitoring via RTSS, the frame time intervals collapsed from a chaotic 12ms - 35ms range down to a tight 9ms - 14ms, and the game finally felt fluid. I did run into two Blue Screens of Death (BSOD) during the initial setup, but everything stabilized once I dialed the ring bus frequency back from 4.8GHz to 4.6GHz. The CPU now stays around 65℃ - 72℃, which is manageable. After four grueling rounds of Cinebench stress tests, the clocks aren't dropping anymore, and my RAM temps are hovering between 58℃ - 63℃.
