Hi Brad,
There is a minor problem with loading OBJ dataset in Performer v2.2.

The pfLoader converts the OBJ dataset to a _single_ node, whatever the OBJ
file contains many sub-objects in it. Therefore, Performer calculates whole
geometry data all the time even if only small portion is in FOV.

You can easily check this by opening the OBJ file with perfly, then enable
database hierarchy and count the number of triangles shown in the scene.

The new OBJ loader in the version 2.4 is a little better, but it looks like
that it splits the nodes based on surface color or material info.
