How do I fix the slow turn calculation loading bar in Sid Meier's Civilization VII with my Great Wall GW3500 1TB?

I felt helpless watching the loading bar stall during turn calculations. I tried raising the queue depth to 128 first, but it had no effect on latency, which felt like a futile effort. GamePP indicated the default 64 depth was the bottleneck. I used GamePP NVMe Queue Depth Config to increase it to 256 and enabled TRIM. Benchmark tests showed 4K random read speed rising from 50MB/s to 75MB/s. Turn calculation time dropped from 15 seconds to 8 seconds. This tweak allowed me to export my strategic plans without the annoying delay.
