Undocumented option: Smooth lines

I forgot to mention this in the README . . .
Ctrl+X toggles antialiasing of lines. Orbits and contellation lines look much better with this option enabled. I don't have it turned on by default because I don't know how it will affect performance on various graphics cards. It does seem to work fine on all GeForce cards at least.

Ctrl+X works with Radeon and it looks much better.
No problem with the performance.

It works just fine on Radeon 8500.

Small performance hit on my Laptop's 16meg trident adapter.
Obviously this isn't a 3D card though, and some OpenGL stuff not supported, or supported partially. Eg eclipsed planets turn completely black and sparkle like an event horizon on acid (quite a nice effect, really), and I get some strange, dark radial spikes and shadows that fluctuate on Saturn's rings as you view it from different angles. Is there a way to selectively disable specific command-types from inside Celestia?
Interesting note: upgrading drivers dramatically decreases performance and number of supported extensions. Sigh. What I get for buying a laptop I guess.
cheers for a great prog

I'm using the Mac OS X port of version 1.2.0 on an old beige G3, which has no hardware acceleration for OpenGL whatsoever, due to Apple wanting me to buy a new computer already instead of waiting for them to support my ancient Rage Pro.
Anyway, I see the same thing you described. Instead of the planet casting a shadow on the rings, the entire antisunward half of the ring system is covered with this weird-looking network of radial black spikes that vary somewhat with the viewing angle. Since I hadn't seen any other complaints, I assume that a system with real 3D acceleration wouldn't show this.
