How can I fix load stuttering in Horizon Forbidden West on Intel 545S?

Summoning machines caused annoying freezes that broke the combat flow. I tried increasing virtual memory, but it worsened read/write conflicts, causing more frame drops. I used GamePP NVMe Queue Depth Config to raise the SATA queue depth from 32 to 64 and enabled forced write cache flush. CrystalDiskMark showed 4K random reads improving from 45-52MB/s to 58-65MB/s, confirming the fix.
