so, I heard things about Vsync limitng frames thus lower power consumption, less tearing.
so does it really do that? i keep it off because i like to see the fps all the time. BUT is it better on or off?
less system stress?

V-sync keeps the frame rate the same as the refresh rate fo your monitor, hence no tearing, If your GPU is pushing more FPS than the refresh rate then V-sync is better turned on in my opinion, but then i dont like tearing in games....

It will have no effect on the power consumption if you turn it on...

You cannot see FPS...unless you are talking about something like Fraps which is showing you tthe FPS whilst you are playing.. Once it goes over a certain amount, you do not see any more as that is the speed that your eyes and brain can see and calculate... I have heard people say that some can see a higher FPS than others but am yet to see proof of this, In my honest opinion, 45fps is no different to me than 60fps or 100 fps, but then maybe that is all my brain can cope with lol...

30 FPS is commonly used as the bare minimum a Game should run at for smooth gameplay! i like this figure for RTS RPG MMO games but do prefer 45+ for Shooters though.

Just as Moricon says, if you're producing more FPS than your screen can display, then turn Vsync on. This stops the next frame arriving from the graphics card before the screen has finished drawing the last - so you end up with some of frame 1 showing with some of frame 2 (which shows as tearing).

If however, you're producing the same or less FPS than your screen can display, turn Vsync OFF! When you hit under 60 FPS, Vsync will limit you to only exact fractions of this number, so 30, 20, 15, 10 FPS, etc. This means if your card is able to produce approx 55 FPS, Vsync will actually limit you to 30.

Best advice IMHO, turn Vsync off always and then enable it only if you notice tearing in that particular game.

VSYNC is only really worth it when screen tearing is excessive and constant, or if you are playing a game where you already extremely high framerates.

its not worth the performance hit when often you wont notice a difference in quality.

Actually, I simply leave it on. For one, I've never had the issue of frames dropping down to 33 with Vsync on (I'm still wondering exactly where that came from), and it helps save some extra work on both the CPU and GPU side overall.
