Celestia - Explore the universe
Authored by: lamon on Nov 08, '05 01:54:47PM

This comes from some ATI graphic cards not understanding a specific OpenGL extension. If you uncomment that line, you disable the use of that extension (for a small performance penalty) and it works.

Remember, the more powerful your video card, the better. It will work better on a NVidia card since the developers are on NVidia.

While it's true that the lead developer is employed at NVIDIA, on the Mac the situation is a bit different and some NVIDIA-specific render paths don't work even on NV30+ cards. And while it's true that very recent cards are obviously much better for Celestia use, the crashing bug is due to a very specific bug in the driver for the ATI Radeon 9000/9200 cards and has nothing to do with your video card being too old; for example ATI Rage cards don't lock up. In fact, recent video cards still cannot perform OpenGL 2.0 rendering correctly on OS X while on Windows it's beautiful *sigh*
