Well, that's the runway lighting problems? The reason is well known to me. We do triangles in point mode using back face culling to get the directional lights. Enabling point sprites in this mode is something fglrx does not like since some time. The open source driver can go well with this without any fallbacks. This one has other prolems, so just suggesting the oss drivers is not yet a real option. I dont think that this kind of problems also apply to a possible cloud implementation. What you would do for clouds is much closer to the particles in osg. And these also work for fglrx.
