The FPS or frames per second is the amount of times a screen can update in one second. The higher the frames per second the smoother the animation and motion on screen. You may have seen TV’s advertised with 120 hz refresh rate.
This is simple to translate into frames per second as the equivalent of 120hz is 120 fps. If you imagine what happens when you create an animation on a notepad and flick through the pages in 1 second, an animation with 120 pages will be smoother and more fluid than that of an animation with 60 pages.
Previous generation consoles were limited to 60 fps but we rarely had games which fully utilized this. This was mostly down to limitations and resources used elsewhere like graphic fidelity. Games were mostly released running at a max of 30 fps on PS4 and XBox One consoles.
What are the benefits of 120fps?
If you have a display that is fully capable of outputting 120fps while gaming, you’re essentially going to see more frames than you would if you had a screen capable of only 60fps or 30fps. 120fps coupled with a low input lag are a great combination, enabling you to see more detail faster with smooth motion. Low input lag and 120fps will allow you to enable you to respond to events in your game that split second faster.
