Why does Red Dead Redemption 2 stutter during scene transitions?

Scene transitions in RDR2 were a nightmare, with write speeds crashing from 6500MB/s to 1200MB/s per CrystalDiskMark. I tried disabling write cache flush, which caused multiple disk disconnections. I then used GamePP NVMe Queue Depth Configuration to set the depth to 4096 and adjusted the cache strategy. CrystalDiskMark showed 4K random reads jumping from 50-55MB/s to 72-78MB/s. Loading times dropped from 8s to 3s, and temps held at 48-55℃ via GamePP. This fix worked perfectly.
