The frame rate in a video game represents how often the screen refreshes to render the image. It is usually measured in frames per second (FPS).
Why High FPS is Important
Areas that can affect a game's frame rate/FPS include:
The graphics card and CPU are the main factors that contribute to the frame rate or FPS performance of a game. The computer's CPU sends instructions from programs to the graphics card. The graphics card (GPU) then processes the received instructions, renders the image and sends it to the monitor for display.
There is a direct relationship between the CPU and GPU, where the performance of your graphics card is dependent on the CPU and vice versa. If a CPU is underpowered, there is no point in upgrading to the latest graphics card if it cannot utilize all of its processing power.
