General Performance & FPS Questions & Answers

Performance trouble is not always a low FPS counter. A simulator can report high frame rates yet feel choppy because frame times are uneven, while overheating may trigger CPU or GPU throttling during longer flights. This hub covers those symptoms alongside stutters, slow scenery loading, limited Prepar3D performance and the common main-thread bottlenecks found across flight simulators.

The Fly Away team’s tested answers help identify whether settings, add-ons, drivers, cooling, memory, storage or hardware balance is responsible. Guidance explains which options usually load the processor or graphics card, how to check temperatures and frame pacing, and when an SSD improves loading and texture delivery without materially increasing FPS. The aim is stable, repeatable performance rather than an impressive but misleading peak figure.
