Why do textures load late when parachuting in STAR WARS Battlegrounds?

During fights at air-drop points, building textures would load three seconds late, leaving me wide open to ambushes. I initially tried closing all background Windows updates, but this had zero effect on hardware bottlenecks. I used the GamePP NVMe Queue Depth Config to increase the depth to 2048 and optimized I/O scheduling. CrystalDiskMark showed random 4K reads rose to 72-78MB/s, and AIDA64 confirmed SSD temperatures stayed between 45-52℃.
