How can I stop frame drops when large creatures spawn in the open world of Death Stranding 2?

I noticed stutters whenever large creatures spawned, with throughput dropping from 25.6GB/s to under 12GB/s. I tried setting virtual memory to half the disk space, but it increased conflicts. I used GamePP NVMe Queue Depth Config to raise depth from 512 to 1024 and enabled forced write cache. CrystalDiskMark showed 4K random reads jumping to 55-62MB/s, and loading times dropped from 8s to 3s. This set my expectations for smooth play.
