Graphic Cards Some Info on VSync required

Hmm, I've heard everywhere that Vsync should be disabled for better gaming. Now it ostensibly has something to do with the monitor.

I was thinking the other day that since I've spent a fortune on a LCD :ohyeah: will enabling VSync do any good.

Could anybody please elaborate ?
 
well if you dont like the tearing of images while playing those high graphics games , you should just enable Vsync . other than that , there is absolutely no improvement in image quality !

Vsync maintains that the graphics card send the frames to the monitor at the specified refresh rate of your monitor . just move around alot in Doom 3 or something with vsync off and on . you will see the difference . I mean i dont like those tears and all .
 
its like the lines formed herizontally when u shake your screen really fast (with the mouse ofcourse)
Its very obvious in CS 1.6 as it runs on OpenGL, but its hardly noticible in the new games...

It doesnt make a Difference.. Stick without it... all it does it kills your fps to half.
 
V-sync for life, feels a whole lot better.
There would be no real reason to turn it off if every game supported triple buffering.
200fps on 100hz is useless.
 
V-sync doesn't kill your fps in half, lack of triple buffering does.
Doesn't matter how godly your refresh rate, games will always feel better v-sync'ed (ie if the game can do triple buffering, else turn it off).

@yogi1771
It should be off by default and will only be turned on when you enable it from the game.

On the contrary, refresh rate is what determines the actual frames which you see.
VSync merely coincides a refresh with the display of your front frame buffer. :)

The sole purpose of VSync, AFAIK, is to prevent tearing of graphics; if there is none, better to leave it off as, IMHO the extra frames serve to improve the visual quality.

I ran CS Source with AF on 16x and AA on 2x and V-Sync on i got 60 FPS.
w/o V-sync i got 130 FPS.

Go figure.

Vsync means that the fps will be locked to the refresh rate of ur monitor. That means it'll stick to 60fps in case of a panel (60Hz refresh is the standard on 99% of the panels). So any frame rate higher than refresh rate will cause screen tearing. Thats the job of vsync.... locking the frame rate to a particular value :P.

So, is it weird or smthin, on my lappy i am getting about 210 hz refresh rate :S :huh: on ati m6 32 mb chipset/card...???!!!!

Is something wrong with my display as there is option to stretch it even till 250 but i fear that , smthin weird wud happen!!!!!!!!
 
^^Those higher numbers are probably doing nothing... The driver is fooling the OS into thinking that a higher refresh has been applied. Its still running at 60 Hz.

That's why I said games always 'feel' better v-sync'ed.
200fps at 100hz is jittery crap, while even a 60fps at 60hz is slick smooth (although eyes get raped) + better display quality as all image tearing goes away.

Even if there is no tearing, I say v-sync be enabled.
You can actually feel the mousing smoothness especially in quake3 powered games.

Again I assume the best case scenario where 100% of the games out there support tripple buffering or you have a godlike pc that won't ever drop a single frame from whatever your current refresh rate.
In a realistic scenario, enable v-sync as long as tripple buffering is present, else disable it.

But why you think extra frames serve to improve the visual quality is beyond me.
Extra frames will just smooth up the gameplay or did you mean extra frames leave a margin to turn up the game details a little further ultimately improving display quality.
 
Ok, ok the reason why I posted is my LCD is at 1024x768 @ 75 Hz and it can't go beyond that. So will enabling VSync on a LCD do any good ?

I got the point mentioned by Saumil and Ein but then thats for CRT's where you can change resolution and Refresh rate.

Anyways, thanks for the help I will try with VSync and post back :D !
