Been around quite a while, and like others, never had a problem with the previous green graphics. I did (and still do) have a problem with 10 ft putts on tourney greens still rolling up short to the hole when I've thumped it 10 ft hard!!
I've also noticed that I used to be able to get a smallish grid around the hole in chippng mode/flop mode. That seems also to have disappeared. ATM, I have to switch to putt mode to get an idea of green borrow before switching back to whatever chip mode I want.
It actually showed the grid in a chipping mode once - so it seems to be very inconsistent as to when it does what it's supposed to do.
The dot size means nothing to me - but in all honesty, I don't really like the look of it, and again without being offensive, I can't see how it helps any more than the previous graphics.
