VSync - On or Off?

I always turn it off. Games get more FPS that way and I don't really notice the difference with the VSync on.

I'm not really sure what VSync does, but if screen tearing is horizonal lines going through the screen while playing I've had that happening only in Torchlight 2 and I found it really annoying, so I turned VSync on for that game. I'm currently on my laptop and it's definitely not a beast, so the least graphical options I turn on, the better.

I always play it with ON. dont see a reason to have it off. tbh

start with it off, turn it on if there's tearing

No one should turn it on unless there's screen tearing in the game. Turning it on lowers FPS significantly.

I want the most fps possible so not on for me.

Off, since I've heard it hurts FPS.

I turn it on. It eats up power unnecessarily and it can also lead to tearing with it disabled.

Off, gotta go fast

On, one time i put off, the fps passed 200 and overheat the card

I leave it on the default setting.

So much complaints that it CAUSES FPS DROP, loled hard.

I always try turning it on in all games. Since it removes screen tearing it's of course best if it can be on, but in some games it causes mouse lag but it's always worth trying.

off so my card heats up and I don't have to turn on the heater in this cold days

Depends on the game really! Usually off though.

I have it on whenever possible. It eliminates screen tearing. Plus there's really no benefit of your card putting out more frames per second than your monitor can render, it's just wasting system resources.

i keep mine on while playing leauge of legends, it caps my fps at 120 and when its off i vary from 117-130, capped fps at 120 and it doesnt cap without vsync

i also dont know what it looks when it tears, idk if ive never seen it or it doesnt happen to me

I turn it off if the game isn't running smooth enough with it.

I keep it on, because in some games you see ugly horizontal lines.

Since Dead Space 1 (which was almost unplayable for me) I turn it off most of the time, just for prevention.

I leave it on to prevent my laptop from burning (really helps to keep temperatures at bay)

If you have an Nvidia card then you can go into the control panel and set your Vsync to adaptive, that way if your fps goes above the refresh rate, it will turn on Vsync, but when your fps drops below the refresh rate, it turns it off. That way you won't get big fps drops. So that's what i always use.

I think a lot of people don't quite understand what it is.

VSync caps your FPS. Now, normally people would scoff at this. "I want the maximum FPS possible!" they might say.

However, VSync only caps your FPS to what your monitor can display.

For instance, you might have a monitor that displays 120FPS. Now, say your graphics card is outputting 140FPS. VSync would cap it to 120FPS - so, because of your monitor's limitations, you wouldn't be able to tell the difference. (It's impossible for your monitor to display the full 140FPS, so what's the point in letting your GPU output 140?)

Now, you might be asking what the big deal is. So what if my GPU outputs 20FPS more than my monitor can display? Why should I care?

Well, the problem is that, even though your monitor can only display 120FPS, the GPU still forces 140FPS (this is with VSync off). This causes tearing, which is characterized my lines forming (usually horizontally) across the screen. This is your monitor trying to 'catch up' with those extra frames by displaying extra frames whenever available, even if the timelines don't quite match.

So, there's really no point in leaving it off unless you're experiencing some sort of incompatibility (which doesn't happen too often). By turning it on, there is no visual loss, plus you prevent tearing.

Depends on the game. Sometimes off, sometimes on with triple buffer. Never without triple buffering though.
