Fix Simulation Save Lag
Managing a million-person city was a pain because every save caused a 1s freeze, which is deadly for simulation. I tried disabling all background update services, but the frame drops persisted, leaving me totally exhausted. I used GamePP NVMe Queue Depth Configuration to lock depth at 512 and enabled forced write cache flush. Random read latency dropped to 11-16ms per RTSS, with frame times at 5.1-6.4ms per GamePP Analyzer.
