This means that many games now have the overhead to run at a superior 60 frames per second, and in some cases, 120 frames per second (though you’ll need a compatible TV for 120hz gaming). With a new generation of consoles, many of the hardware limitations that necessitated frame rate locks have been removed. This is done to ensure consistency while playing so that players are less likely to notice big dips in performance when they occur. The frame rate was largely locked at 30 for the last generation’s big titles.
“FPS” stands for “frame per second” and refers to the speed at which a game runs.
