Your monitor or display is where refresh rates come in. Refresh rate is measured in frequency (Hz) which is the number of times per second your monitor can redraw the screen. A refresh rate of 85Hz means that your display can redraw the entire screen 85 times in one second.
Does that mean that your frame rate is limited by your screen’s refresh rate? No; they are two separate things. Remember that FPS is how many frames your PC is producing or drawing, while the refresh rate is how many times the monitor is refreshing the image on the screen. The refresh rate (Hz) of your monitor does not affect the frame rate (FPS) your GPU will be outputting. However, if your FPS is higher than your refresh rate, your display will not be able to display all of the frames your computer is producing, so although the refresh rate doesn’t technically limit the frame rate, it does effectively set a cap.
