Vsync questions

post #1 of 23
Thread Starter 
From my understanding, Vsync is just a simple frame limiter that locks at 60 FPS in order to go allong with the usuall 60 hz monitor to reduce or remove tearing.
If you were to have 120 fps, double the 60, wouldn't that result in a same effect, meaning no tearing?
and 240/480/and so on.

But what about 30 fps? and how about 66, 72, 78, 84 and 90 ?

The reason i'm asking is because i'm wondering if i can lock my fps higher then 60 on a number that will remove tearing but also improve my responsiveness (less input lag)
If i can lock at 78 for example, that's doable. 120 fps will be really tough on games like Battlefield 3 smile.gif

It's a little more complicated than a frame rate locker.
It actively syncronises the rate of frames calculated by the gpu to match the exact rate of the monitor using a buffer.
I guess that the vsync rate depends on your monitor should it be 60 or 120 .

The easiest way to reduce input lag with v-sync on is to turn off all AA. This isn't discussed often but works.

Do you reccomend using a frame limiter locked at 60 fps with Vsync? or should i just use Vsync and leave the frame limiter off?

I see no point in doing that as the vsync will already limit the frames .

Thanks for clearing that up.
But what if u have 120hz? how do u even begin to use Vsync? I don't think most single cards reach 120 fps in games like battlefield when running every at max settings.
Or crysis 3. How do people prevent screen tearing then?

They use Vsync too. Hitting 120 FPS is often achieved with dual high-end cards or lowering settings as some people see that 120 Hz is more smoother than 60 Hz and they reach 120 FPS with a single card by turning down settings to enjoy more smoothness.

If you run a 120hz monitor, will you have benefit from it at 80 fps for example?
Also i read about Tripple buffering, people say it reduces tearing a lot BUT does introduce more input lag.
And what about AMD's CCC. I'm not on my computer now, but i can recall reading about forcing Vsync onto games from CCC, is that a better option then going with the ingames' vsync?
And how do people deal with imput lag? running 120hz Vsync seems cool, but then having 200 fps might be even better, not on the eyes but the input lag will be further reduced?

The thing is when someone wants to buy a 120Hz monitor it's most likely a competitive player (most of the times). Competitive players usually play games like Counter-Strike 1.6, Counter-Strike: Source, Counter-Strike: Global Offensive, League of Legends, Dota 2 etc. Those games are usually pretty much all the time running 120+ FPS with a decent hardware. I used to play competitively Team Fortress 2 and with a highframes config I'm getting peaks to 1100 FPS which might sound crazy but it's true. So basically what I'm trying to say is that most of the players are usually lowering the gfx settings in-game to achieve highest possible FPS to improve their game especially when it comes down to aiming and such.

Edit: Also enabling VSync in 50% of games causes huge mouse I/O latency.

It's kinda related: does vsync lock your framerates to your monitor refresh rate or just 60/120 Hz? Why I ask is because I overclocked my monitor refresh rate recently to 70 Hz and I was wondering if vsync would still work.
