disabling vsync

[Anarchist420]

If Vsync is diabled and the monitors refresh rate is 60 and the frame rate is 45 fps, then is tearing severity calculated by the following equation (100%=terrible tearing, 0%=no tearing)?:

100%/x=60/45

So in other words, if the frame rate is 45, vsync is off, and your monitor's refresh rate is 60Hz, then will tearing be 3/4 as bad as it would be if the frame rate was 60fps? Or is tearing the same at 15 fps as it is at 45 fps (60 hz refresh, vsync off)? Or does tearing happen more when the frame rate fluctuates by a large amount?

I'm asking because I want a happy medium in regards to tearing without the added input lage of Vsync. I'm able to put up with limited tearing, a frame rate as low as 30fps, and just ~15ms input lag (~13ms input lag of my monitor+2ms input lag from my mouse).

every game is completely different. some tear insanely bad no matter the framerate. in fact some of the worst tearing I see is in games where I have the lowest framerate. at the same time many games where the tearing does not bother me usually have really high framerates way way above 60. plus some games noticeably tear even when just firing a gun or encountering flickering lights.

for your viewing entertainment here is Metro 2033 tearing really bad even with 25-30 fps. http://www.youtube.com/watch?v=RkO8U8r2Tf8

Try to reduce the pre-render frames to 1 or 0. It helps when you have lots of GPU resources.

Vsync on for ever.

To not see tearing and you must able vsync on and triple b on ,

People wouldn't put up with tearing during a Movie so i don't know how they can during a game. Vsync + Triple buffering, never had input lag problems.
