Edit: It seems the correct way to test this is to start with a value of 2 and keep on decreasing until the lag is gone. It doesn't terribly improve the frame rate (think it actually hurts it) but just removes lag problems. Advisable only if you have a less powerful card.
Where is this setting in the control panel? I don't have it or an "Additional D3D" settings tab with my 84.25 drivers.
