Hi joe,
It may benefit you to clear your flash and browser caches. Your browser stores game and course files in its cache. Sometimes those files can become outdated or fragmented and that can slow down the initial load period. Clearing your cache every time we announcement a product update is a good way to stay up to date with the most current files.
Please note that when you clear you caches it also resets your in-game options, so if you have any preferences for graphics quality or flagstick animations those will need to be reset before you tee off. Depending on your connection speed your first round or two may load slightly slower than normal while your PC re-caches the necessary files, but subsequent rounds should load faster.
