Do some people buy a 144hz monitor and turn vsync off ?

You might ask why I ask this question, but here is why.  Getting capped at 120 or 144hz meants you wont see those 180fps and 200fps performance.  Do people turn off vsync with a gaming monitor so their framerates are not capped but the monitor is still doing its job with smooth play.  Biggest question is does it cause image tearing as I have never experienced a gaming monitor to know.

Because v-sync sucks a big one.  144hz monitor reduces tearing at high FPS without v-sync.

For esports and competitive games, no, you leave it off. More FPS, the better, regardless of refresh rate. Some games I leave it on if I'm hovering around 60-80 fps at 4K to reduce stuttering/lag.. Which I hardly see at high FPS for some reason..

Vsync gives loads of input lag so id never enable it.

Wow that is great news.  Thank you Karath and ChewToy my master guru.  I currently have 60hz monitor and vsync off gives tearing.  But I guess what I learned is is if you have a 120 or 144hz monitor turning off vsync does not make things tear.  That is amazing if that is the case.  Tearing sux big time and vsync on messed up your fps.. sighs.

Just be happy you're not a 30fps console peasant

There can be tearing on 120 or 144Hz monitors, you just cannot see it that well since the picture is updated much more frequently.

I see, I see... thank you for that easy explanation.

Vsync introduces lag and limits your hardware. If you have a lagspike at 200 fps to 150fps its not so bad but when it dips from 144 to 100 its more noticable.

Regular V-sync (without triple buffering) caps the fps to the set refresh of the monitor. But it has side effects - if your framerate drops below the refresh rate it limits the FPS to half (it's dual buffered), so if you're using 60Hz and your framerate is above 60 it will limit to 60 fps but if it drops below 60 it will limit to 30 fps and show the same frame twice.

Let's say your system is able to output 100 FPS yet you use v-sync with a 60 HZ screen, your framerate will be limited to 60FPS with many frames dismissed - that buffering of the complete frames is what causes latency and thus causes input lag. And when the FPS drops below 60 it limits to 30 FPS and then the difference is even more noticeable.

It's easy to calculate the latency to see the impact on input lag - 100 fps means 1 frame is rendered each 10 milliseconds (1/100 of a second), 60 fps means 1 frame takes 1/60 of a second - 16.6 ms. On average, a trained human (a combat pilot, a race driver, a gamer) notices differences in the range of 13ms but the effect is cumulative - a game run at 60 fps for a time period seems less smooth than a game run at 100 fps.

A good read: https://www.pubnub.com/blog/how-fast-is-realtime-human-perception-and-technology/

Triple buffering in V-sync allows for a lower performance drop if the framerate dips below the refresh, but it still isn't ideal.

Tearing occurs when the graphics card output isn't synced with the monitor refresh. it's not always a bad thing - you don't want v-sync in multiplayer shooter games.

Gsync + nvidia vsync -> way to go on 144hz
