I have the G5 in my sig and OS X 10.4.8. In age of empires 3, I see some annoying graphic glithces using high or very high shadow quality. This is what I get with high quality or very high quality shadows during the game. When trying to move the camera, the shadows are changing, and they flicker all the time. I am forced to disable shadows to get rid of the problem. I have a very fast computer, and I think that this should not happen. Anyone else with this problem? How can I get rid of it?
