Frame time measures the time interval between individual frames displayed on the screen, providing a more detailed view of frame consistency compared to frames per second (FPS). An ideal frame time for a game running at 60 FPS is 16.6 milliseconds per frame, and deviations can lead to stuttering. A frame time graph shows frame time in milliseconds on the vertical axis and frame number or recording time on the horizontal axis, with a flat line indicating optimal performance. Gamers often prefer consistent, lower FPS over fluctuating higher FPS for a better experience. Troubleshooting frame time issues involves examining CPU and GPU utilization and adjusting settings. Keeping video drivers updated is essential, and persistent issues may indicate problems with the game itself, as seen in titles like Gotham Knights and Elden Ring.
