A little table (GeForce4 MX 4000, 1280x960) for fgfs --timeofday=midnight: point-sprite enhanced-lighting fps runway/taxiway lights =========================================================================== false false 18 steady pixels [1] false true 2 steady thick points [1] true false 11 dim and blinking pixels [2] true true 11 steady thin points [3]
[1] Identical to CVS < 20060126.
[2] Nice for christmas, but otherwise completely broken. This is what
I get without the patch.
[3] Best attempt at looking like a real airport, I'd use this on a
more powerful system.
Enabling line-smooth removes about 7 fps from these figures.
See the attached patch (I think point-sprite and line-smooth should be
disabled by default).
