V-Sync actually synchronizes the framerate with the display device's refresh rate so that the frames get displayed at proper times. In practice, this means that if, for example, your refresh rate is 60 Hz but you can't hit 60 FPS reliably, it'll cap your FPS to 30 FPS. And if you can't hit even 30, it'll cap it to 15. Half V-Sync supposedly does exactly the same, expect that the cap is at maximum half of the display device's refresh rate, so it shouldn't solve any problems, I think.
I'd also like an explanation as to why the same problem doesn't apply to consoles because to me it seems like it should. It's exactly the same technology as far as I know.
Also, 30 FPS looks bad on both PC and consoles. More importantly though, it feels bad.
