Hi palupear,
Generally when you're experiencing large amounts of timeouts like that there is an issue with the files stored in your browser's cache. Try this...
- Optimizing Your WGT Experience <-- Click that link and follow the instructions near the bottom about clearing your Flash and Browser caches. This will delete the stored game files on your PC. *NOTE* clearing your Flash cache will reset your stored game options
Once you play your next round the game will re-cache the files to your system. During the first round of play you may experience slightly longer load times while the files are downloaded, but it should clear up after that.
To help improve performance I would recommend trying to set your graphics quality to LOW in the game options. If you have the putting grid option ON, turn it OFF. Even set to OFF the grid will still be displayed on the green until you initiate your backswing. You can also try playing in a smaller window and/or closing the WGT website in the background and only having the game client open.
Hope this helps =)
