Why does No Rest for the Wicked stutter during catacomb loads?

I felt my immersion shatter as background processes ate 14.2-16.8GB of RAM, causing visible character lag. I tried cleaning temp files, but it did nothing to fix the bottleneck. I used the GamePP Resource Scheduler to set the game process to Real-time priority and switched to High Performance. Per GamePP Benchmark Verification, frame generation dropped from 12.1ms to 8.3ms. HWiNFO showed stable temps at 58-63°C. The system finally feels smooth and responsive.
