The back 9 of St. Andrews is nearly unplayable for me, once was enough to see it had more meter trouble than the front 9.
Again, it is unusual for me to have meter trouble. I have followed the tweak guide, have a fine connection, and even use both google chrome and firefox, with the same performance trouble.
If others get metered, please use the right click on screen report method at the time and place of the trouble so maybe they can figure it out easier.
