Why do I need V-Sync on all games?

Hi Guys,

I recently bought a 6870, which I am very pleased with, but I have to enable V-Sync for all FPS games, otherwise I get horizontal tearing.

This isn't a massive problem but i am limiting my fps to 60 by enabling.

Just wondering why really, do other people have this problem?
 
I also got a sappire 6870 recently and have had no problems with needing v-sync in games, just make sure you get the latest drivers from the amd website exact for you build. You can also try fiddle round in CCC to see if you have enabled anything you didnt mean to.

I actually like VSYNC on in games and bumping up the eye candy. General question to all, am I missing out by limiting my system to 60fps?
 
Also vsync can introduce input lag, which is almost as annoying as screen tearing in some games. A better solution is frame limiting
 
You still get tearing with frame limiting. But aye, it will remove the mouse lag associated with vsync which can be important for competitive on-line gaming.
 
Yes, it's why Vsync exists :)

the tearing is just a mis-synchronisation between your graphics card buffer and monitor refresh

you don't need more than 60fps for smooth gameplay and if turning on vsync fixes the tearing issue then surely that's a good thing?

if you want to benchmark your card for bragging rights then turn off vsync, but if you need it on to stop the tearing then turn it back on!

i hope this helps
 
I don't have an ATI card to hand, but in the Nvidia control panel, you can set the following options..

Triple buffering - ON
Force VSYNC - ON

This means you don't have to touch the in game settings and don't ask me how, but it doesn't have the input lag that some games introduce with their own setting
 
Yea...as much as I would like to enable vsync to remove the horizontal tearing, I can't stand having my mouse feeling like dragging an old women along with it...so I have not choice but just try to ignore those tearing.

MSI Afterburner's frame capping it's good though...it does somewhat make games smoother, and it doesn't put unneccessary workload onto the graphic (frame rate beyond 60fps) and making the card consumption more power and run hotter to generate higher frame rate which out standard monitor ain't able to display.

That all sounds good, anyone know if you can do that with AMD cards?

No. If you are using a 60Hz monitor then the monitor can only draw 60 discrete frames every second. It doesn't matter how many frames the GPU is trying to send to it they won't be outputted. It can increase fluidity to disable Vsync due to the decrease in input lag but if you don't 'feel' a problem with Vsync on yet see a problem with it off then there's your answer. :)
 
Vsync isnt what some people think it is, people think that if you have a 120hz monitor or you dont go above your refresh rate you wont get tearing and dont need to use Vsync.

Vsync sync's your GPU with your monitor and has nothing to do with their being more frames than your refresh rate, without Vsync you get screen tearing even if your fps is below your refresh rate (for example 60 fps on a 120hz monitor), its just that its less noticeable in that situation and allot less noticeable on 120hz but still very much there.

Vsync also has input lag, so depending on your setup and the game your playing if they dont tear too bad, if you can handle some tearing if it isnt that noticable then you can have Vsync off and reduce the input lag.
