If it lags then reload the page and that should fix the problem if not, Then I can't really tell ya what to do. on my computer, I have to reload it several times and do it on full-screen mode for it to stay perfectly in sync. otherwise, it lags horribly. also it kind of needs a fast computer to run well so yeah...... be careful
Heart and star if you think it syncs well and looks good (and ONLY if it meets GOOD standards) EPILEPSY WARNING
