A user reports a significant performance issue in Microsoft Flight Simulator 2024, noting severe frame rate drops during nighttime operations. The problem occurs across all major airports and affects all aircraft within the simulator.

The user observes stable daytime performance at approximately 116 FPS, which falls sharply to around 90 FPS or lower at night. This FPS drop has been confirmed at multiple major airports, including Hong Kong International (VHHH), New York JFK (KJFK), and London Heathrow (EGLL), indicating a widespread issue rather than location-specific or aircraft-specific causes.
