In Bioshock, this can clearly be observed at the beginning of the demo where you're going up in the "sphere" and that "thing" attacks the sphere, causing the sphere to light up with blue lights. If Vsync is off, and the FPS are above 60 or below, then the whole screen starts to flicker, one part being blue the other being the regular color.
Tearing happens any time the frame rate doesnt match the refresh rate. It doesn't have to exceed it.
But yeah, that scene is terrible without vsync.
Its too bad the game runs so much slower with it on.
I had to turn it off to get smooth frame rates in some areas (vsync gave me low 20's in some places, with it off I got around 40).
