FPS - Frames Per Second, or First-Person Shooter.
In this case, FPS means Frames Per Second. Having 7 FPS means that your game is updating the screen 7 times every second, or compared to a television, maybe even a computer screen, 7 Hz.

Having a FPS of 7 is usually totally unacceptable, especially in a fast-paced First-Person Shooter game such as AA, since aiming will be extremely difficult. An absolute minimum of 20-30, or an average of 40+ should be required in all games at all times.
