V-Sync is not stopping screen tearing

[darkely]

I turned V-Sync on in the options menu, and the screen still tears (as if it's off).

My GPU settings are not overriding anything, before anyone asks that. I'm using an Nvidia GeForce GT430 (1GB), I know it's old, but it still plays the game well enough. I know I can force the game to do it through CP, but I'd rather the games setting do it, as it should.

EDIT: I just noticed this thread, but I didn't want to hijack their thread. Maybe a moderator could merge the two? if needed anyway.
