Why does my Huntkey Blizzard T600 cause stutters in towns?

Whenever I hit the crowded streets of Bohemia, the screen just hitches for a fraction of a second, making the controls feel completely unresponsive. Checking HWiNFO, the 12V rail on my Huntkey Blizzard T600 Colorful was jumping wildly between 11.7V and 12.1V during transient power spikes, which triggered a brief protective clock-down on my CPU. I initially tried toggling 'Ultimate Performance' in Windows, but that actually made the voltage swings worse—a total nightmare. I eventually dove into the BIOS Advanced Voltage settings, set the Load-Line Calibration to Medium, and disabled C-States in the power management tab. After that, the voltage stabilized to a tight 11.9V - 12.1V range, and my frame times dropped from a messy 18-45ms to a consistent 12-16ms. It wasn't a smooth ride; the system had some weird boot delays after the first tweak until I added a +0.02V offset to the Vcore. Now the PSU fan sits at 1100-1300 RPM and the stuttering is gone. My hands finally stopped shaking from the frustration.
