Animation is slow!

Hi all,

This is a pretty simple question. I have a fairly good computer that’s been working well for me. I recently followed a tutorial in which armatures are used with the sapling addon. The person in the tutorial had his computer work fine, but my computer was very slow and took minutes to respond to every click. I had to turn armatures off. Is there a reason my computer is being so slow with animation? Is there a way to increase the memory cache limit to make it faster?

Thanks,
Joseph

How many polygons in your scene? Do you have any subsurf modifiers on any objects?
