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

[Andy Zupko]

Flash stores those textures (power of 2 textyres) in the l2 cache so  
they are faster to retrieve.  If you use BitmapMaterial.MIP_MAPPING =  
true (or whatever the command is) then it should do it for you  
automatically.  It is not mip-mapping in the typical meaning of 3d.    
I think this is only done up to a certain texture size, but i'm not  
sure what it is.

I would also make sure:

1) tiled = true for your material
2) check your thumbnail code to make sure its not running when it  
doesn't need to be: use bitmap caching until the mouse is over the  
area of interacting with that menu, stop all recalcuing of positions  
and such unless the mouse is near it. (often times pv3d is greatly  
affected by the 2d stuff left running in a project)
