Andy's right Mac, you've been a member for a while now, and your first post is a complaint about the swing meter?
There is plenty of things the members can do on their end to maximize their experience at WGT.
1.) Defrag your computer on a weekly basis.
2.) Stop useless background, and start up processes during game play.
3.) uninstall unused programs
4.) Download Game Booster from Cnetdownloads.com, a trusted download web site.
5.) Optimize your computer using Advanced System Care, a program that can be found in Game Booster. It's free, and it works.
There really isn't nothing WGT can do with the Adobe flash program, it is what it is. Like the guys said, it's all we got for now. Everyone plays with the same swing meter and deals with it accordingly. Keeping-up with the simple tasks above, you and everyone else at WGT should have a better experience with the game.
Good luck and play well.
*Edit: I forgot. Last, but not least for sure, don't forget to keep your
Adobe flash, and browser caches cleared before game play.
