Vsync option
 

Just what is the vsync doing for me if I check it on the options page?

Limits the framerate to your refresh rate.

Helps with "shearing" if your not having any problems with it leave it unchecked (shrug).

And this does what as far as FPS or clarity of the picture?

Shearing? What does this look like?

Imagine a photograph ripped in half and put back together a little off.

Except the lines would connect like this smeared or warped.

Has no real effect on "frame rates".

I think the guy means "tearing" which as you move the camera around would tear the image........hard to explain but easy to notice :)

SteamWake beat me to it :lol:

OK, cool. I did not have this issue with 1.1. I have the option checked in 1.2. I guess then I do not need this option checked as I do not have the tearing or ripped looking picture. Yes?

No not if your picture is fine when looking around...............I've had tearing alot in other games and v-sync sorts it out :)

Scroll down to second screenshot of mine. This was with the 1.1 patch. Pic looks good to me. I guess I do not need this option. Thanks for the help men!

Only notes CRT. I use a LCD. I'm turning this option off. Seems I do not need it.

Strange I too have an LCD and I need it :-?

Glad you don't :D

One thing I noticed, and maybe it's just me, but after fixing this problem in the config file in 1.1 it went away. But in 1.2 I still have shearing even with vsync enabled in the graphics options. I double-checked in the config file and it's still selected there too. Very annoying.

Not quite as annoying as the audio crackling I have to fight through but there I can't decide how much is SH4's fault and how much is the Vista/Creative debacle messing up my day. At least turning off some graphic options, yes graphic options, cut down on it enough so SH4's playable.

Using V-sync can also eliminate or at least minimise potential problems where frame-rates can sometimes vary from 2fps to over 100fps, which can cause instability in certain configurations. With V-sync enabled, the disparity between lower and upper limits is minimised, resulting in less unforeseen lock-ups and crashes. The down-side is that it "caps" or limits your maximum frame-rate to either your current refresh-rate, or half that value.
