V-sync

What is V-sync ? What is the use, effect and quality in gaming?

 

Any help wille be appreciated.

 

V-sync (Vertical Synchronization) matches your monitors refresh rate/frequency, with a 3D applications frame rate. In other words, it won't allow your frame rate to rise above your monitor's refresh rate.

Also, it fixes any "tearing" you might see in games. For example, when playing Crysis I notice a green fuzzy bar on the top of my screen, but when I enable V-Sync, it disappears.

Granted, I'm not an expert on V-sync, but I hope my explanation helped.

 

V sync puts a cap to your fps. Meaning it fps won't go beyond that cap.

It also helps deal with tearing. I usually turn on my v-sync in nvidia's control panel and not in game.

In dead space, if you turn on vysnc ingame, fps caps at 30. If I do it from nvidias control panel, fps caps at 60.

If I turn it off completely, I experience a lot of tearing in areas with shaking and lighting effects.

 

Yep, that is correct.

BTW, turning it off will increase FPS, if thats what you are intersted in.
Through the NV Control panel.

 

It removes the fps limiter, doesn't necessarily mean your fps will go higher.

 

oh, ok.

But it at least makes it seem like it, and usualy play better.

 

It can play better without vsync, because very often when your fps drop below 60 fps they plummet down to something like 30 fps. That kind of drop is extremely noticeable. There is a trick to fixing that though. If your gpu has enough memory you can enable triple buffering in the game or in the driver control panel for the gpu. This feature is highly dependent on how much vram your graphics card supports and enabling it on a gpu without enough memory could make things even worse.

 

Nvidia gpus are notorius for hating vsync. I always get better fps without it. I turn it off and crank things enough to negate my gpu's ability to go above 60 anyways. Unless I'm playing an older game.

 

Oh really? Ill have to go enable that now. I think i have enough VRAM. lol
Ill see how it helps! Thanks.

 

So is it good or bad then?

 

I can't play any games without vsync on, the tearing and stuttering ruins the experience for me

 

ok...
so its good for gaming but need a good system

 

Yes you need a good system but not as good as you ware thinking lol.

 

Ok nevermind.

 

Thank you.

I read your post then went into nVidia and put vsync on in there and turned it off in Dead Space and what a difference! I'm not sure about some people but when I had vsync on in Dead Space it was hard to effectively move the mouse in the menu, but when I turned it off in Dead Space the mouse moved smoothly. I wish I found this out before since I believe I have almost beat the game.

Now I just have to tweak Fallout 3. Unfortunately it crashed last night when I was talking to Three Dog. Don't want to go off-topic but anyone have help?

Now about this buffering. Would I benefit from doing that trick?

Thanks.
