Question about vsync and screen tearing?

Something of a quandary...

If there are any fixes so i can run CoD without vsync on, does anyone know?

I have:
AMD 965 BE 3.4
8 gB RAM
2 x 5830 in Crossfire
LCD Dell ST2410

Ive asked this question myself and here is an explanation.

V. VSync On Or Off?

Ok let's look at this a little closer because the answer is different for most people and also is dependent on the game. *VSync works hand in hand with triple buffering.

VSync ON = Matches the frame rate to your screen refresh rate for seamless and capped 60FPS performance.

VSync OFF: Maximum frame-rates are achieved over 100FPS+ However, if you have a really awesome video card you may be pumping out too much FPS vs frame rate and "screen tearing" or "page tear effect" will occur:

100FPS+ but "tearing effect" with VSync Off

More feedback:

Vsync on:
-Perfectly aligned frames, no tearing.
-Less likely to crash.
-Locked at you're monitor's refresh rate. Usually can only go to 60 FPS (mine goes to 75 FPS though... somehow)
-FPS can bog down more then vsync off.

Vsync off:
-Virturally unlimited FPS....
-More likely to crash, but the difference is generally pretty low. (It depends on the card and the game)
-FPS does not bog down.

Let your immediate needs determine if you need V-sync on or off, based on the advantages and disadvantages.

It takes mere seconds and zero effort to turn V sync on or off and judge the results accordingly.

I have found recently with my most updated rig that "Vertical sync....Force On" in the NVIDIA CONTROL PANEL for the best results with no tearing.


Conclusion: One is not better than the other. It based solely on the results on your screen
