FPS is an abbreviation for Frames per Second, which translates from English as "frames per second". Frame rate is a numeric metric that shows the number of frames per second that change on the screen. The concept is used both in cinematography and in modern computer games.
In cinema, frame rate is used to reflect a constant frame rate throughout the film. This indicator in the cinema is equal to the standard 24 frames per second, the flicker of which is considered invisible to the human eye. The 24 FPS standard was introduced in 1932 and is still used in cinematography today.
On modern digital IMAX systems, frame rates reach 48 FPS, but each eye still recognizes 24 frames. The increase in frame rate was done to improve the displayed quality of 3D effects in stereo glasses. Similar to cinematography, the frame rate has been kept constant in television.
Computer games use a frequency that is generated by the software (the game itself) and displayed on the screen. This frequency largely depends on the performance of the computer. Modern games can be divided into two types: constant and variable frame rates. Games with variable frame rates will display different frame rates on strong and weak computers. Games with a constant frame rate show the same picture on both weak and strong computers.
Measuring FPS on modern computers is used to test the performance of a gaming system. There are special programs that allow you to find out the number of frames received at various graphics settings that require a stronger computer configuration. The application for determining the number of frames per second allows you to fine-tune the display settings in any modern game.
Riva Tuner can measure the frame rate on the screen. During the game, the performance can be shown by the easier-to-use Fraps. EVGA Precision also has a tool to display the frame rate of an image on the screen.
For a performance test, you need to download one of the above programs to your computer from the developer's official website. After downloading, run the resulting file and install the software according to the instructions on the screen.
Run the installed program using the shortcut on the desktop and activate the FPS display setting. After that, you can run any video file or game for performance testing. The number of frames will be displayed in the upper left or right corner of the screen.
