V-Sync question form a noobie.

[K i a r a]

Hey, 

 

SO 

Odd question, but I was wondering about the whole vsync thing - I understand what it is and everything,

But this is what I dont get.
I have a 60hz Monitor so every game I ever play i lock to 60fps. Due to when i DONT it looks soooo choppy, for an example Minecraft I get like 300+ FPS, But when I dont have v-Sync its so laggy. and when I lock it to 60 its fine, Yet I also still drop to like 55fps .-. 

But this is my real question, How can people with 144/240 Monitors play with no v-sync and its not choppy? 

Also, with that in mind, How come when they lock it with vsync they say "This is horrible looking" and such

You can't get 55fps with v sync. It's either 30 or 60 with your monitor. Because the game engine needs to maintain the fps at 60 to make sure there is no tearing. So if it drop to even 59 it will automatically drop to 30 that is why v sync is often associated with stuttering because it went from 60 to 30.

Because the monitor can truly display those frames. Or at least most of it.

Probably because of the stuttering.

Vsync is based off off your monitors refresh rate. If you turn it on there is no point in capping the refresh rate, it will automatically cap the rate to your monitors refresh rate/half the refresh rate. 

 

Vsync doesn’t stop “choppyness” it actually can add to it. When you drop below 60fps with vsync on you will encounter a stutter as the refresh rate goes from 60 -> 30. what vsync is actually meant to do is prevent screen tearing. The image is rendered from top to bottom, and if the full image isn’t rendered before the refresh window you will see a screen tear. For instance if you’re at 55fps on a 60hz monitor some of the images displayed on the monitor will be made up of 2 different frames. This is less noticeable on a higher refresh rate monitor, especially if you’re running around ~90 FPS, since the tears will be made up of two more similar images.

 

if running your monitor uncapped with vsync on causes stutters, I would cap the game to like 120fps then turn on vsync.

That's actually kind of a myth, it's only true for double-buffered V-Sync, which hasn't been widely used for a long time. Almost everything uses triple-buffered V-Sync, in which case the framerate doesn't have to be integer fractions of the refresh rate anymore.

Isn't that will increase the delay even worse?

You’re right in the fact that it doesn’t cut it back to 60/30 but the change in frame rate like 60/45 under triple buffer will still cause stuttering when it transitions.

Why would it?

Yes, although it's not any different than an uncapped framerate in that regard.

It’s not quite the same as uncapped from my understanding, but it does eliminate some of the downsides of vsync. If you’re rendering over rendering over the frame rate, like OP is he should use fast sync (assuming he is using an Nvidia card).

In regards to stutter it should be the same as uncapped
