I've tried the old forum search with no results again. Please explain the purpose/benefits of VSync and its effects of turning it on/off on gameplay.

as i under stand it it keeps objects like land scape from showing tearing or seprating on my pc i have run it on and off and havent seen any performce hits so i just leave it on

It's the synchronization of your monitor refresh rate with your gpu refresh rate.
If your gpu refreshes faster than your monitor and v-sync is on stuttering will result.
On the other hand if v-sync is off and monitor refresh rate is set too low tearing will result.
Your best bet is v-sync off and monitor refresh rate as high as possible.

IMHO, v-sync on with highest refesrh rate supported.

Anyone who tells you to run v-sync off has no clue.
Vsync on means that your computer won't begin to draw the next frame until the first one is done being drawn on your monitors screen.
People like to turn off vsync to artificially inflate their benchmark scores. Their computer is only drawing a half frame, then going to the next. They see their FPS score go up but they aren't really getting that many frames per second if they aren't really drawing complete frames (duh)
To see the bad effects on image quality that turning vsync off causes, run the game in Open GL (DirectX will not vsync in IL2/FB) and select "vsync off" in your cards OpenGL settings. Then get a plane on the runway with the cockpit and look around with the mouse. If vsync is off you will see the cockpit bars getting ripped up as they travel across the screen.
Conversely, if you want to see the advantages of vsync on then run the game in open GL (DirectX will not vsync in IL2/FB) and select "vsync on" in your cards OpenGL settings. Then get a plane on the runway with the cockpit and look around with the mouse. If vsync is on then as you pan around with the mouse the cockpit bars will remain solid.
Never play a 3D video game with vsync off. "Vsync off" is refered to in modern games (like SWG) as "allow image tearing" (which is bad)

Your nuts RBJ with vsync off on my machine the game looks fine, and it keeps the frames from topping out.
I don't know what type of machine you run, but i have never had a problem with screen tears or any other distortions for that matter.
May you not become a dirt torpedo.

PlatinumDragon, you are way off base. Why do you think vsync is there? And why do modern games refer to vsync in the settings as "allow image tearing"???
Because vsync-off causes image tearing!!!
If you can't tell the difference (open GL only...DX does not vsync in IL2/FB) then I truly feel sorry for you.
It doesn't matter what rig you have, if you arent in sync then there will be image tearing with vsync off. If you can't tell the difference then you just aren't very observant.

From http://www.themeter.com/faq.shtml#why which should answer the question "V-Sync defined please?".
Why do you test with VSYNC on? Don't most gamers turn VSYNC off?
Actually, we test with both.
For a number of reasons, we lean toward VSYNC On, but we do use VSYNC Off to ensure that our test results aren't misleading.
In fact, testing with VSYNC On and VSYNC Off are both valid methods of testing. Care needs to be taken in interpreting the results of either, however.
VSYNC is a term used to describe how a graphics board renders and displays an image to the display. With VSYNC On, the graphics board draws one frame of a scene, and waits for the monitor to display it before starting the next frame.
With VSYNC Off, the board draws one frame, and then immediately starts on the next frame - whether the display is ready for it or not.
Except under unusual circumstances, benchmarking relative performance (that is, board x is 30 percent faster than board y) with VSYNC On can be misleading. However, testing with VSYNC On or Off yields consistent rankings (board x is number 1, board y is number) - provided that all boards are tested under the exact same conditions.
VSYNC ON testing will compress the relative performance difference between boards that are fast enough to max out the frame rate at the monitor's refresh rate. Example: Board A can render at 76 fps, but maxes out at 75 fps because of the monitor, while board B can render at 150 fps, but also maxes out at 75 fps. Both Boards A and B will appear to have the same performance.
The key to testing with VSYNC On is to load the boards so they don't max out at the refresh rate. As long as at least one frame of a test scene renders at less than the display refresh rate, the true rendering performance will be seen, and the boards can be ranked fastest to slowest.
Testing with VSYNC OFF can show how fast a board can render scenes, regardless of whether the scene is actually displayed. Most games are actually played with VSYNC ON, so that VSYNC OFF may give an unrealistic relative performance measurement.

Exactly. Vsync-off is only for benchmarking.
Vsync-on is a must for image quality during play.
