Play on the "off peak" times, it makes a world of difference for me.
If I play from 9 - 11:30PM Eastern time I am almost guaranteed to have meter stutter, graphic loading issues, game loading issues, they all go together.
When I play on off peak times the game is totally different.
When I play at like 3 in the morning, the game plays like a DREAM, perfect everything, no sign or whiff of a stutter at all, I can play 18 flawless holes.
Someday WGT will upgrade the servers and this will fix some of the problems for people, of course people with too many process's running in the background etc will always have issues. IF you can, try to play the off peak times.
Hope that helps.
