Can FPS be set too high?.

Hi all.

Can FPS limit be set too high?. I seen that people say set your limit to Screen refresh rate x 2 + 1. So your 60hz will need a 121 fps cap. So I have a 144hz screen should I set mine to 289 or would this be to high with everything on max settings it can go on latest games?.

Generally any FPS higher than the refresh rate of your monitor can cause screen tearing, particularly at 60Hz which i find particularly noticeable. I generally cap my games at 60 when using my 4k display as I hate the input lag you get form using v-sync.

If I am playing a twitchy FPS on my 1080p 144Hz monitor I tend to leave the fps cap off, as any tearing occurs much more infrequently and is far less intrusive.

The idea with setting the cap at refresh rate times two plus one with 60Hz was to:

-Minimise input latency
-Render in a way to minimise the amount of tearing perceived with v-sync off
-Not have the GPU churning out 1000s of FPS in menus, etc. with v-sync off which can cause noticeable whining noise and cause the GPU to use a lot of power when it doesn't need to

Its not so relevant with 144Hz especially if you have freesync or g-sync - though its still a good idea to cap around 200fps or so if v-sync is off to minimise power use, etc.

Hmm it tried that and it seemed to make no difference whatsoever, i tried playing gta with vsnc off for a while and i was getting around 200 fps, so i figured capping it to just over 120 might help smooth things out as it was jumping up and down a lot, but it seemed to just make it worse for me. Maybe its crossfire related.
