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.
