Why does my Delta Force loading bar freeze at 99% for 5 seconds?

I was losing my mind during war zone map loads; my Zhitai TiPro9000 Limited Edition 4TB showed weird sawtooth fluctuations, freezing the progress bar at 99% for 5 seconds. I first tried closing all background services in Windows, but I/O utilization stayed above 95% per HWiNFO, and the freeze persisted. I then used GamePP NVMe Queue Depth Configuration to force the queue from 32 to 128 and synced the write cache flush policy. In CrystalDiskMark, 4K random reads jumped to 68-76MB/s, and AIDA64 confirmed temps stayed at 45-52℃. Total relief to finally save
