How to Implement an FPS Counter

https://vplesko.com/assets/how_to_implement_an_fps_counter/graph_fixed_cnt_roll_avg.png
To accurately display FPS, use a rolling window of frames from the last second and precise timers, calculating the average processing time and then the FPS value from that. This approach provides a smooth and consistent FPS counter that is less affected by individual frame processing times and can be easily extended to track other performance metrics.
