In WoW's Valdrakken hub, my ASUS ROG Z890-A Snow has constant micro-stutters. Fix core switching?

Every time I hit a crowded player hub, my FPS would just dive from 120 down to 45, which is honestly exhausting. The default power management on the ASUS ROG STRIX Z890-A Snow was flipping between low and high loads way too fast, causing the core voltage to jump between 0.8V and 1.3V. I tried the Windows High Performance power plan, but that only gained me 5 FPS while making the stutters more frequent—a total waste of time. I eventually dove into the BIOS Advanced settings, completely disabled C-State energy saving, and locked the minimum processor state to 100%. HWMonitor showed the clocks stop jumping from 2.1-5.2GHz and stayed steady at 4.8-5.2GHz, with frame times dropping from a messy 15-40ms to a tight 8-12ms. My idle temps jumped by 10℃ after killing C-States, so I had to fix my case airflow to get it back to 45-52℃. CPU power is now 85-110W and VRMs are at 55-60℃. No more drops, it's finally sorted.
