Hi Scott
Without getting too involved in it, as I hadn't noticed any difference, I've had another look. Playing with a Vapour ball the vapour trail does it's usual thing, depending on the shot length, fading out slowly but tracing the length of the shot.
With the option turned off in the game settings, on the short shot I looked at, there is what looks like a comet's tail following the ball, a set length then fading away, not following the entire path/flight of ball but giving a rough indication.
Best of Infamous" the par3 water hole, Congressional.
Dry, and almost sunk! Not the best idea to pick black for the trail but it was the first I laid my hands on. Usually a *SPLOSH* gives me a better idea where my ball ditched. . er landed.
Happy Easter, take care
Cheers!
