Vsync locks the FPS to a multiple or a divident of your refresh rate.
That is, say that your refresh rate is 85, then your FPS will always be 85, or 85/2, or 85/3, or 85*2, 85*3, etc..
Prevents tearing, but at least in ET it leads to strange behaviour..
It doesn't lock the FPS. A single frame is always displayed to n/85 seconds (where n is an integer >= 1) with vsync enabled, but n can vary over time.
If FPS without vsync varies between 70 and 100 FPS (with 85 Hz refresh rate) then some frames will be displayed twice as long as others, which makes it really jerky, and actual FPS will average somewhere between 42.5 and 85.
IIRC, RivaTuner wouldn't let you go under 2, but the driver settings (might need Coolbits enabled?) would. However, there's also a separate registry key for OGL prerender.

But as with anything, try and see if you like it!
thx dude
