Short definition: FPS stands for frames per second and describes how many individual images your computer renders each second in a flight simulator.
Detailed explanation: In flight simulation, FPS is a basic measure of visual performance. A higher FPS usually makes aircraft movement, camera panning, instrument updates and scenery loading appear smoother, while a lower FPS can make controls feel less responsive and the display look uneven or jerky. FPS is affected by hardware performance, simulator settings, screen resolution, traffic levels, weather effects and complex scenery or aircraft. It is useful for checking whether a simulator is running consistently, but FPS alone does not describe every aspect of smoothness, because short pauses and inconsistent frame delivery can still affect the experience even when the average number looks acceptable.
Key considerations:
- A practical limitation is that very demanding scenery, weather or aircraft systems can reduce FPS even on capable hardware.
- A common mistake is focusing only on the highest FPS number instead of aiming for stable performance during normal flight.
- A real-world impact is that low or unstable FPS can make taxiing, approach and landing harder by reducing visual smoothness and timing cues.
