So that may be the answer for people who work with insane amounts of point data.
Regretably I have run into performance limitations with datasets that would not typically be considered "insanely large". Aerial imagery and DEM files have been issues for me and others. However since I am limited to a 32 bit environment those problems may not occur so readily in a 64 bit environment.
If I may interject some insight I may have in regards to the performance issues with C3D and Autocad, I've noticed that when I load some of our Land Desktop drawings into Microstation, performance in Microstation is incredibly snappy by orders of magnatude. Inquiring into why this might be I was told by a member of Bentley's development team that the difference is likely due to ARX technology. When a file with ARX components is opened in Autocad, Autocad is constantly scanning and updating those objects for or when any action my cause the objects to change (i.e. changing to a 3D view orientation of a surface object requires a different display state for the object). Since Microstation does not support the dynamic state of ARX objects (they are loaded as ProxyGraphics), it is not affected by the refresh process.
I have noticed significant performance degredation with each release of Autocad in recent years and I suspect this is due to an increase in the number of ARX components implemented in the format. If I am correct then I expect the performance issues with C3D and Autocad are going to continue to be a plague until there is a change in the paradigm.
