Why does Rift Apart crash during dimension jumps on 16GB RAM?

It was unbearable; the moment a dimension jump occurred, the game crashed to desktop, wiping out all my progress. I first tried closing all background programs, but memory usage still spiked instantly to 95-99% via GamePP. I then entered the GamePP Resource Scheduling Panel, manually set the virtual memory to 16GB, and set the game to high priority. Peak memory usage dropped to 12.8GB per HWInfo, and memory frequency remained stable at 3200MHz per CPU-Z. Temps stayed at 45-52℃ per AIDA64.
