ASD, in performer2.2, will provide several different features.
1. paging
It will support a flexible eye point centered paging scheme
that will allow you fly high and low, far and near...
Terrain will get coarst instead of broken if paging
can not catch up with the rendering evaluation.

2. use a new thread COMPUTE instead of DBASE for evaluation
COMPUTE thread should be useful for user's geometry computation.

3. support clipmapping better
when clipmap manages very large texture ( >32k), geometry
needs to be grouped to best support the texture.

4. support morphing or color, normal, texture coordinates and
multiple geostates.

5. multi-channel and multi-pipe

to name a few.
