Adantages and Disadvantages of V-Sync?

#1JirynPosted 8/21/2013 7:38:02 PM(edited)
What are the advantages and disadvantages of V-sync?

I have a decent computer most games run between 80-120fps.. however while playing Saints Row 4 I noticed constant screen tearing.
During game play it's not that bad, but quick cutscene camera cuts and etc it tears like mad.

So, I am curious as to what all would happen if I were to start using V-sync more often.
Someone told me using v-sync causes input lag and a performance decrease.

I'm confused by this lately.

Cthulhu saves the world screen tears like crazy if you turn on vsync. But with it off, it plays nice and cleanly.

Advantage: Fixes screen tearing.
Disadvantage: Lowers framerate.

I'd think it'd be fairly obvious.

If Vsync actually works, it eliminates screen tearing but locks frame rate at certain intervals. So, for instance, vsync on some games will lock the frame rate to 60. If you would ever at any point drop a little below 60, it jumps down to 30... so if your computer isn't really great, then you'll also suffer some wildly inconsistent frame rates.
If vsync doesn't work properly, then you'll encounter screen tearing AND your frame rate will still be lowered.

Right. Triple Buffering can help with this problem.

That's what I thought, but as I said someone said it caused input lag as well.

True. Some games don't seem to have noticeable input lag, others are terrible in this respect. Just personal experience.

Why? How?
Most games have little to no tearing but god SR4 has to much.
