I haven't performance tests on using user defined clip planes and many
points, but I have done a far amount of performance testing on points
and geometries, my 7800GT can comfortably handle over a million
vertices per frame at 60Hz. My 6600Go laptop doesn't quite keep to
60Hz with a million vertices per frame, but it not far off.
Using VBO's and chunking of the data certainly helps, so batch you
data is sets of spatially similiar locations, such as 10,000 vertices
per chunk has worked well for me in the past. I'd recommend creating
data in programmatically so you iterate how big chunks you use.
Robert.
