Vsync makes no difference if you're running at 25 fps.

In fact disabling it might actually make things look worse
by introducing visible "tearing" of the image by updating
out of sync with the monitor.

("tearing" is horizontal lines across the image caused by
having half the image showing one frame and half showing
another).



we can't list each card in the system requirements.

That list basically says "every graphics card ever" so I
wouldn't worry about it, support is pretty much guaranteed.
If not, see above - "vsync makes no difference".

[ There's a slight weirdness in the list, "Intel" only has two
entries but I know for a fact that more Intel chips can do it.
eg. my laptop has a 945GM graphics chip and it reports
the extension (as it should - this is very basic stuff).]
