I did a quick and dirty test today to compare Away3DLite to Away3D
3.5. I found that with 500 planes tweening in small groups the
difference between the two libs was pretty small. Away3D 3.5 ran at
about 18/24fps and Away3DLite ran at about 20/24fps. I'll post the
code that I used for each test. I'm wondering if there are things that
I can do to make everything run faster and push more polys.
