FPS is the abbreviation of first-person shooter (game proper term). FPS (the first personal shooting game): Strictly speaking, FPS belongs to a branch of ACT game, but like RTS game, FPS has developed into an independent type due to its rapid popularity around the world. FPS is defined in the field of images (frames per second): the number of frames transmitted per second. The number of frames per second is more accurately defined as "the number of frames per second to fill the image (frames per second)". FPS is a measure of the amount of information used by the frame panel to save and display dynamic video. Generally speaking, it refers to the number of pictures in animation or video. For example, in movie video and digital video, each frame is a still image; Displaying frames in rapid succession will create the illusion of motion. The more frames per second (FPS), the smoother the motion display. Usually, the lowest FPS to avoid unsmooth movements is 30. Some computer video formats can only provide 15 frames per second. The "FPS" here can also be understood as the "refresh rate (in Hz)" that we often say, such as the "FPS value" that we often say in CS games. We will pay attention to the "refresh rate" when installing and purchasing graphics cards and monitors. Generally speaking, we set the default refresh rate above 75Hz (that is, 75 frames per second). For example, the refresh rate of 75Hz means that the screen only scans 75 times a second, which is 75 frames per second. But when the refresh rate is too low, we can feel the flicker and discontinuity of the screen with the naked eye, which has a bad influence on the image display effect and visual experience. Movies are played at the rate of 24 pictures per second, that is, 24 still pictures are continuously projected on the screen in one second. The unit of animation playback speed is fps, where f is the English word frame, p is Per, and s is seconds. Chinese expression is how many frames per second, or how many frames per second. Movies are 24fps, which usually means 24 frames.
