SSAO & VSYNC what does it actually do?

[ATAG_Dutch]

SSAO is some sort of subtle shading of this and that that kills my frame rate.

V-synch prevents screen tearing when using track IR for me but again reduces frame rate.

With my spec I have no choice but to switch them both off.
And AA and epi, come to that.

I thought triple buffering only affected open GL though.

I'd've thought that vertical refresh to 'off unless application specifies' in ccc and switching vsynch on in-game would be best to try.
