I see clock speed swings on my Ryzen 7 9700X in complex areas of Where Winds Meet. How to fix?

This CPU is a total wildcard—insane performance on paper, but it loves to drop clocks right in the middle of a fight. With PBO enabled, my Ryzen 7 9700X was swinging between 4.2GHz and 5.3GHz, leaving me with fragmented frame times between 15-40ms. I tried disabling every power-saving feature in Windows, which just bloated my power draw by 20W without fixing a single stutter; it was just heating up my room for nothing. I finally went into the BIOS, fired up Curve Optimizer, set a -20 offset on all cores, and locked the all-core frequency at 5.1GHz. In RivaTuner, that jagged frame time graph finally turned into a flat line. I actually tried a -30 offset first and the system just refused to boot, so I had to CMOS clear and back off to -20. Now my temps are a cool 68-75℃ with fans at 1800 RPM. I exported the logs via a performance analyzer and confirmed the swings are gone, with fans now steady at 1400-1600 RPM.
