FPS is an abbreviation of the concept Frames per Second which is translated from English as "frame rate per second". Frame frequency is a numerical indicator which shows the number of the changing personnel on the screen in a second. The concept is used both in cinema, and in modern computer games.
Cinema
At cinema the frame frequency is used for reflection of constant frequency of personnel throughout all movie. This indicator at cinema equals to standard 24 frames per second which flashing is considered imperceptible for a human eye. The standard in 24 FPS was entered in 1932 and is used in cinema still.
In the modern digital IMAX systems the frame rate reaches 48 FPS, however each eye will still recognize frequency in 24 frames. Increase in frame rate was made for improvement of the shown quality 3D - effects in stereo glasses. Similar to cinema, frame rate was saved by a constant and in television.
Computer games
Computer games use the frequency which is generated by the software (game) and is displayed. This frequency in many respects depends on computer performance. Modern games can be separated into two types: with a constant and the changing frame frequency. Games with the changing frame frequency will give the different number of personnel on computers of a strong and weak configuration. The games with a constant frame frequency show the identical picture both on weak, and on strong computers.
Measurement of FPS
Measurement of FPS on modern computers is used for testing of performance of the game system. There are special programs which allow to recognize the received number of personnel at the different settings of graphics requiring stronger configuration of the computer. The application allows to make for determination of number of frames per second more thinly settings of display in any modern game.
The Riva Tuner program can measure frame rate on the screen. In the course of the game performance can show and simpler in use of Fraps. EVGA Precision also possesses the tool for display of frequency of demonstration of video frames on the screen.
For performance test you will need to download one of above-mentioned programs on the computer from the official site of the developer. After loading start the received file and install software according to instructions on the screen.
Start the installed program by means of a label on a desktop and activate FPS display setup. After that you can start any video file or a game for testing of performance. The number of personnel will be displayed in left or the upper right corner of the screen.
