I think, that is a bug in the c4d exporter.
I thought it was related to models with bones.
I do not know exactly why, but it is the first picking action, which  
takes so long.
the same model exported from 3DSMax doesn't have that problem.
(In my case it was something like, the very first mouse over took  
1000 milliseconds for the c4d model and 10 for the max model or so)
without knowing any specifics, my guess is, that the mesh is  
precomputed for fast polygon picking algorythms and things like the  
bounding box are cached. while 3DSMax seems to precompute this data  
somehow (or simply store the data in a more optimized way) c4d and  
maya exports take a huge amount of time, the first time you use one  
of the picking functions (modelunderloc etc.)
although the c4d exports are bigger in filesize and worse quality  
wise (the maya exporter is somewhat better in that regard), it just  
seems to be the case, that the 3DSMax exporter yields MUCH better  
results in all regards.

Although I am far away from being a windows centric guy, I always  
push the art department in using 3DSMax instead of any other 3-D app.

the quality is simply the best for sw3d.

you can reduce the polygons on c4d side (there is a modifier/tag to  
do so).
and in director you can set the lod.bias to a lower value and use  
lod.auto = 1 or switch off the lod.auto and mess with the lod.level  
instead.
