What kind of performance change (better? worse?) did you observer?
Thanks,

They are a replacement. The good blink sequence support and attractive
appearance of the OSG light points, coupled with performance problems
I've seen in the past with rendering polys in point mode, led me to go
with the OSG light points all the way. For the point sprites I am using
the existing simgear sprite texture.
