Although Hulk was very over-angry when he posted, I agree with his second point. In two versions ago (the august released version) the fly over tour was perfectly fine and once i opened google earth it worked instantly

two versions later the performance is horrible
i open google earth and i have to wait more than ten seconds before it loads everything and i have a top of the line computer

furthermore it takes about thirty seconds before the flying gets into tune; before that its shaky

even after that its somewhat laggy

two versions ago none of this happened
