Why does Crysis Remastered drop from 90 to 40 FPS on Kioxia EXCERIA G3?

The Remastered version's high-precision vegetation created a massive I/O bottleneck, causing frames to plummet from 90 to 40 during combat transitions. I tried forcing PCIe Gen3 in the BIOS for stability, but this halved the bandwidth and tripled loading times—a counterproductive move that left me depressed. I then used the GamePP NVMe Queue Depth Configuration to optimize the read queue depth to 1024. Verification via AIDA64 showed random read latency converged to 78-84ns, down from 115ns, while temperatures stayed 48-54℃ per HWInfo64.
