will turning vsync ON help with reducing ghosting?

Yes since it'll limit the frame rates it should.

That would be my guess.
BTW 2.8c was a excellent buy man. Cheers!!

Vsync will limit your fps and may slow down your card to even lower fps than limited in certain situations and your response time will be less.

20ms=100fps so if you monitor has that response time or better. Keeping the fps under a 100fps should reduce ghosting if there is any.

how do you get 100fps out of 20ms. I get 50fps.

25ms will be 40fps.

Idk, but I would rather keep native res and refresh rate. The picture looks better that way.

All right now... Do any of you replying to this post own an LCD? Do you know wtf you're talking about?

Vsync stops vertical tearing. That's it. It won't help ghosting, ghosting has nothing to do with vertical tearing.

Raising your refresh rate beyond the native spec (usually 1280x1024 @ 60hz) won't do anything but degrade image quality, in my experience. It won't reduce ghosting.

I use vsync, just like w/ a CRT, to stop vertical tearing. Vertical tearing occurs when your FPS exceed your refresh rate.

hmmm, my LCD is rated at 75 mhz @ 1280*1024 but for some reason it was set it 60, producing a ridiculous amount of ghosting in games, i raised it to 75 and all the ghosting disappeared

Your LCD (which I'm assuming is the AU 16ms panel) is meant to be run @ 1280x1045 @ 60hz. Like it says in your manual. I'm not saying that 75hz will hurt it... Are you sure that the dissappearance of ghosting is just in your head? As I understand it, refresh rates for LCDs have little meaning, and certainly don't make the difference that they do on CRTs.

Rock on! I never allow myself the sin of putting Vsync on, although the picture does look a tad prettier, I would rather experience the game better.

Um... explain to me how vsync IN ANY WAY makes the game worse? How does it damage the game experience? Please, I'd LOVE to hear it. What exactly do you have to gain by making your video card output more frames than your monitor can display?

I swear, if it's not being a CRT nazi, it's being a dumb@ss.

its 25ms response time and according to the website it is supposed to be @ 75 hz. i think its more of the tearing issue you talked about rather than ghost. all the characters in LOTR: return of the king flickered and had lines going through them before i changed it to 75 hz

Tearing is also a very rare occurrence. I have only experienced it one in the past week and a half or so and it was in an awkward situation and did not affect my gaming.

ok, with vsync on, how many fps will i get with a 25ms LCD?

i know it difference from game to game, but for the sake of arguments, lets say i get 100 fps with vsync off

It`s easy to work out FPS speed,1000/25ms=40fps so that`s optimum,just like a 16ms would be 1000/16ms=62.5fps.Expect frame rates to go lower depending on the game,res etc.

It's simple frequency formula. 1 over time will give you the frequency and vice-versa. Ex. 1/.016 for 16ms = 62.5; 1/62.5 = .016 or 16ms.

Which ATI drivers are you using? I'm using Cat 3.9s, and in the custom 3D settings I have Vsync always on.
