Frames

What Is A Frame?

Frame is a single drawing or a picture on a screen.

A game Frame is drawing of 2D,3D or both objects which depend in their positions rotations and scale on game logic, physics ,animation and camera position.

Facts:

• Any screen can only display one static image called Frame at a single time. in case of 60 frames per second the time a single frame will spend displayed at the screen is 1/60 of a second.

• Multiple Frames with slight variation can be seen by human eyes as continuous motion.

• The bigger the difference in delta position of an object in a game the faster its motion across the screen will be and objects that have no delta position will appear static.

• Movies used to be 24 frames per second because its the minimum frames required to give the illusion of continuous motion and 24 is low enough for manual editing (when movie industry started it was the norm).

• FPS means (Frames per second) which means a 15 second video with 24 FPS has 24 x 15 = 360 static frames or pictures in case of a movie.

• 60 FPS game means 1 frame every 0.0166666 second

60 frames / 1 seconds = 1/60 = 0.0166666

• Current absolute minimum FPS which people find it difficult to see continuous motion without is 30 FPS.

• Minimum TV FPS 2021 is 60 FPS.

• High-end gaming screens have 240 - 300 FPS. (2021)

• In a movie frames per second (FPS) is a static number.

• In video games frames punctuate and have different FPS each time.

• The FPS punctuation in games is caused by having different calculations in every frame so some frames have very little calculations like static menus, and others have the hardware resources struggling to compute the complex scene.

• There are methods to reduce maximum FPS usually built in to the game engine, this helps with reducing the effects of FPS punctuation and GPU temperature.

• A well optimized game takes into consideration:

- Average FPS

- Minimum FPS

- FPS Dips

- FPS target of the game

• Every day there is new research and methods created to increase FPS with minimum effect on final frames such as DLSS and FidelityFX Super Resolution are prime examples today (June 2021).

FPS if vital indicator on how smooth a game is running on a specific hardware, running it on better,faster and newer hardware will increase the FPS but most people dont have the latest and greatest GPU or CPU, so developers must optimize their game to run on older less capable devices most on the time.
