I keep getting these annoying stutters in city areas of Final Fantasy XV on my H610M-K, is it the VRM?

Walking through the streets of Insomnia was a total nightmare; I kept hitting these micro-stutters that felt incredibly jarring at 60 FPS. After digging into the telemetry, I found the Colorful H610M-K's VRM was spitting out voltage ripples between 15-22ms, causing the CPU core voltage to bounce violently between 1.1V and 1.25V. I tried slapping the system into 'Ultimate Performance' mode first, but that was a joke—average FPS went up by a measly 2 frames, while the actual stuttering got worse. I eventually dove into the BIOS and flipped the Load-Line Calibration from Auto to Manual L2 mode, then bumped the CPU core voltage offset by +0.01V to keep things steady. Running AIDA64 stress tests showed the clock staying locked between 4.2-4.4GHz, and my frame time variance shrunk from a messy 12-28ms down to a tight 8-14ms. I actually bricked the boot process once with a too-aggressive voltage jump, but backing it off by 0.01V fixed everything. VRM temps sat around 78-85℃. I saved these verified parameters to a motherboard profile, and it's been rock steady since.
