I always suggest,
1) Give your PC a good clear out of all old unused junk, then defrag and disc scan.
2) Experiment with different browsers, a lot of people on here now use either Maxthon 3 or Comodo Dragon. Chrome and IE seem to cause problems for MOST people that use them on here.
3) Download Game Booster and 360 Amigo. Both free, and run before each game.
4) Close all other windows when playing, even WGT pages.
5) Clear caches regularly especially after an update like we had on Tues/Weds.
6) Hold at top of backswing for a few seconds to allow the CPU to settle.
I find those things help but any game based on Flash will never be perfect. I hope that helps.
