The issue may be at your end and not theirs. Try playing in a different browser. I used to play in Opera, my default browser, and was experiencing the same issues you describe. Then I switched to Chrome for golf – a browser I don't use for anything else – and since then the game has been running smoothly. So my first troubleshooting advice would be: don't open any webpages except wgt.com in the browser you use for playing.
