Thanks for this explanation. Why does it only seem to work one way?

about also.
No, i was talking about enhanced runway lightning, this is what i get when running flightgear with this option: --enable-enhanced-lighting
I was not talking about specular highlights.
Why is it so expensive of frame-rate?This is very hardware and driver dependent. Some OpenGL features are
just not implemented in hardware on some display adapters.
The only consumer videocards we have today are from Ati and NVidia, do their newest models support this? If not, then we should move it to the advanced options.
I also want to mention, that MS FS2004 has something similar, but
framerate drop, so there must be another way to display runway lights in such a way.

I've also been confused by the monumental frame drop that even the simple runway lighting can produce at airports such as EGLL.
And I do have a fairly hefty system which has been known to run graphical behemoths like Doom3 at a fair lick.
The obvious response from the 'non-programmers' perspective ie: 'user' is:
"Why on earth do these little dots bring my new Model-X video card to its knees?"
So what's the crack? ;)
Simple answer - too many vertices. Someone will give us the right answer -Erik????

After reading the glPointSize doc, I think the problem is in using point sizes bigger than 1 and point antialiasing at the same time
I can't test it now, can someone do it? just disable GL_POINT_SMOOTH and see it there is an fps improvement
