[Papervision3D] Optimizing performance: anything else I can do?

[Andy Zupko]

Regarding the mipmapping (no, the pv3d team does not want to lead you  
on a 4 hour wild goose chase), but:

add this line of code to your initialization:

BitmapMaterial.AUTO_MIP_MAPPING = true;

If it helps than great.  if not then no loss. Should take < 20 seconds  
to add/test that.  Your textures probably are too large, but its worth  
trying at least.

Regarding below:

Tiled helps with a performance bug in the flash player when very small  
triangles are drawn with smoothing on.  Textures can lock up/slow down  
the CPU on very thin triangles (no i dont have any adobe sanctioned  
blogs for this issue either :P) - again, worth trying
