Why does Project Werewulf stutter when large creatures spawn on AMD Ryzen 5 7500F systems?

I was frustrated by the stutters when creatures spawned, with memory bandwidth dropping below 25GB/s per AIDA64. Increasing virtual memory made it worse. I used GamePP NVMe Queue Depth Config to increase the queue from 512 to 1024 and enabled forced write cache flush. CrystalDiskMark showed 4K random read jumping from 35-42MB/s to 55-62MB/s. HWiNFO monitored stable 45-50℃ temps, and load times dropped from 8s to 3s, making the open world feel responsive again.
