Cutscenes in Horizon Forbidden West on my Ryzen 5 7600X are glitchy during combat transitions. Is my hardware acting up?

HWiNFO showed core temps at 68℃ - 73℃ with L3 cache hit rates bouncing between 92% - 96%. I suspected unstable RAM, so I disabled PBO/Auto-Overclocking in the BIOS, which tightened the frequency variance to ±46MHz. After killing all background monitoring bloat, frame generation latency dropped by 12%, and the cutscene hitches mostly went away, staying within 5% of official benchmarks. Frustratingly, when loading massive machine models, the core voltage still jumps from 1.16V to 1.26V, causing a split-second drop. That's likely a memory management issue within the game itself, not the chip.
