Why is my MSI PRO B760M-A WIFI DDR4 II overheating and dropping frames during the rat swarm scenes?

When facing those massive rat swarms, my frame rate would suddenly tank from 70 FPS down to 20 FPS, which is a total nightmare at 2K resolution. I dug into the telemetry and found the VRM on the MSI PRO B760M-A WIFI DDR4 II was spiking between 92-105℃, causing the CPU cores to bounce erratically between 3.1GHz and 4.8GHz. I initially tried enabling the 'Ultimate Performance' power plan in Windows, but that was a mistake—it just pushed the VRM to 110℃ and triggered a hard throttle, which was incredibly frustrating. I eventually went into the BIOS, manually capped the PL1 power limit at 125W, and tightened the CPU fan response time from 0.5s down to 0.1s. Checking RTSS, the frame times tightened up from a messy 25-60ms range to a consistent 14-18ms. I did hit a snag where the system kept rebooting because I pushed the voltage offset too low, but after bumping the Vcore back up by 0.02V, it finally stabilized. VRM temps now hover around 82-88℃ with a smooth power curve. Everything feels fluid now, though the fans are definitely more audible under load.
