Why does the speed of animation effects change on different computers?
Animations do run differently on different computers, depending primarily on the processor speed and the amount of RAM. If you are doing a lot of animation, you want to have lots of both. It may be that the second computer is not as powerful as the first. Sometimes another problem has to do with screen display speed; laptops with screen types other than active matrix displays are very slow, and tend to lag in displaying things.
