I do agree they generally look really nice. I have a new patch at http://www.bricoworks.com/moore/lightpt2.diff (to save everyone a 50k mail message). This fixes the performance problem; I now get the same frame rate, if not a little better, with the OSG lights. There was a problem in my support for switching between point sprites and points. > > I was confused about what the array of view options (sprites, enhanced > lights, etc.) did with respect to this new patch ...

The "Use Point Sprites for Runway Lights" and "Enhanced Runway Lighting" should work as expected. "Runway light distance attenuation" doesn't do anything because that is always active.
As far as the original lights go, they don't have the blink sequence support of the new lights. Perhaps people with old hardware could give this new patch a try and see if it is adequate? > > Another thing that would be nice is to be able to keep the sprite based > mechanism so that lights have fuzzy (rather than hard) edges as they are > rendered. That should work. If it doesn't, can you send me the details of your hardware?
