Frame rate
From Styleguide
frame rate
The number of individual image frames a game is capable of producing in a given amount of time. Usually measured in frames per second; fps acceptable after first reference when paired with a numerical value. See example.
Frame rate should not be confused with refresh rate, which measures how often a monitor or TV updates its image. Refresh rate is measured in hertz (Hz acceptable on all references).
Example: Dance Dance Revolution games on the PS2 run at a silky smooth 60 frames per second. This makes them much more playable than older versions, which ran at 30 fps.
Wrong: framerate, FPS, 30fps, f.p.s.
