Still under 50% on the meter... maybe in the 35-40% range. So it hasn't been too bad, nor do I experience lag on my CPU, which can be on the lag sensitive side. Outside of the buildings seen from hole level, it thins out behind. So if you were to fly around with the scout cam, it won't be a truly authentic experience. I'd say more people than not won't do this, though, so from eye level it at least will retain a somewhat authentic feel. I probably have a handful of buildings left to plant in the 1st/18th area, and only a tiny amount of small buildings spread throughout the rest of the plot. In other words, I think all will be ok.
Targeted settings at the moment are firm and somewhere in the slow to medium range for putting speeds. The settings work well on my Old MacArthur course, but only play testing will confirm if it works for the Old Course or not.
