Well, not so great. At SFO at night in the UFO I see a decrease from
about 60fps with the existing lights to 43 with the OSG version. I
suspect the slowdown is very dependent on processor speed; I hadn't
noticed it on another computer using the debug builds. Although the
distance attenuation does look nicer, you might want to hold off
integrating my patch until I investigate further :)
