Why does my Jginyue B760M cause massive frame drops in Black Myth: Wukong during heavy combat?

During those intense combat sequences in Wukong, I noticed my core temps jumping 15℃ in just three seconds—it was an absolute thermal rollercoaster. The VRM on the Jginyue B760M GAMING just couldn't handle the physics load, with temps hitting 96-102℃, which forced the CPU to throttle and tanked my FPS from 80 down to 40. I tried lowering the shadow quality in-game, but that only gave me a measly 10 FPS boost and didn't stop the stuttering. I had to get aggressive: I set a manual CPU voltage offset of +0.03V and crammed an extra high-airflow fan into the front of the case to blast the VRM area. In HWiNFO, the core temps dropped from 94℃ to a stable 70-76℃, and the throttling stopped completely. I actually BSOD'ed a few times at +0.03V, so I had to bump it to +0.05V for true stability. Now the board stays around 62-68℃ and the frame generation is a smooth 5.1-6.4ms. It's a budget board, so you really have to fight for every degree of cooling.
