NVMe Queue Depth Optimization
The Manli Nebula drive was overflowing its SLC cache during story loads, dropping read speeds to 1500MB/s per CrystalDiskMark and extending waits to 10s. I tried increasing virtual memory, which only lowered overall frame rates and made the stutter worse. I then accessed GamePP NVMe Queue Depth Configuration to raise the depth from 1024 to 2048 and set power management to High Performance. CrystalDiskMark now shows 4K random reads at 75-80MB/s, and loads are down to 4s with drive temps at 48-55°C. It's a huge relief.
