My Colorful CVN B760M FROZEN WIFI D5 is dropping frames in the fog scenes of Silent Hill 2, can I fix this with process priority?

In those oppressive fog scenes, my framerate was acting like a rollercoaster, diving from 60 FPS down to 25 FPS—it felt like a joke given my hardware. The L3 cache hit rate on the Colorful CVN B760M FROZEN WIFI D5 V20 was tanking during complex particle effects, leaving the CPU starving for data. I tried disabling all shadows in-game, but the visuals turned into a pixelated mess and I only gained 3 FPS, which was honestly laughable. I headed into the BIOS, ripped off the CPU power limits, and enabled the high-frequency memory mode. HWInfo showed the core clocks stop jumping between 3.2 - 4.8GHz and settled into a stable 4.5 - 4.7GHz range. I actually pushed the overclock too far at first and the system froze on the loading screen, but backing the voltage offset to default solved it. VRM temps are 65 - 72℃ and RAM is at 50 - 56℃. I exported the frequency curves to confirm the dips are gone, with fans steady at 1400 - 1600 RPM.
