Why more FPS Does NOT Always = Smoothness

Many people think that 100-200+ fps is something to be extremely proud of, or that 200fps will make your game look smoother. Well I'm hear to give you the truth, it just makes the game look worse.

There are two kinds of frame rate issues that will cause jittering, too many FPS and too little fps (which is more worse out of the two).

Problem being is actually your monitor. Your monitor has a fixed refresh rate or hertz (hz) as you probably have heard. This can vary from 30hz, 60hz (most common), and all the way to 144hz. Basically, the 30, 60 or 144 means how many frames per second the monitor is capable of outputting to your eyes. When your frame rate is equal to your refresh, you get perfectly lovely smoothness. :)

Many claim that 200fps gives them better performance over 60fps on 60hz, this is simply not true. Sure it might help a little, but the consequences of running 200fps at 60hz is going to give you headaches.

What you'll get for running a high frame rate at a lower refresh rate is tearing. Simply put: Because the graphics card is throwing so many frames at the monitor, the monitor overloads and now tries to put two-three frames in one refresh. That's why you'll see a tear in between two or three frames, it's like stuffing your mouth with food at a faster rate than what your capable of chewing thru.
The same can be caused with too low a refresh rate, tearing will also occur because both the frame rate and the refresh rate are out of sync.

A simple way of fixing both issues is to turn on V sync. V sync does two things: 1, It caps your frame rate at your refresh rate if your frame rate is very high, giving you very good fps while also conserving energy (less load on GPU). 2, When your frame rate goes below the refresh rate, the monitor will not allow tearing, so instead of displaying two frames in one refresh, it will display the current frame twice or more until the next frame is ready for display. Unfortunately this introduces another issue, lag, because there is a delay until the next frame gets displayed, you will get a noticeable lag in games. However, if your not playing a high speed game like FPS or racing, then the lower frame rates won't bug you.

The only way to fix all these problems is to buy a new monitor with a variable refresh rate or adaptive sync. Adaptive sync a new technology where the monitor will sync it's refresh rate to the GPUs FPS output, so if your outputting 43fps or say 77fps, the monitor will adjust it's refresh rate to 43hz or 77hz on the fly. Allowing zero lag and jittering at nearly all frame rates.

I hope this helps, I've seen a lot of people loving the fact that they can output 200-500fps in CSGO that I felt compelled to write this short tutorial on why it's actually useless to have such a frame rate.
