vsync

[themac]

Today I thought about the vsync option turned on / enabled. When done, it may happen to me that the fps drop below 60. Then vsync goes one step down giving me 30 fps. At this point I save my game, turn off the vsync and get 45 fps for example. Much better than 30. So why not offering a adaptive sync mode that turns of the vsync when the fps drop below 60 to avoid loosing some more fps by cutting down to 30?

Why would you sometimes want tearing on your display and sometimes not?
Does a human eye actually catch a difference between 60fps and 30fps?

I personally see the difference between 30 and 60 fps.
