Anyway, I recently bought Anachronox from Gog.com

Why not ask on the GOG.com forums, then? http://www.gog.com/forum/anachronox/

Yes, there are knowledgeable people here, but if you are seeking people who may be familiar with the problem you are experiencing, surely the GOG.com forums would be a better place to look?

I vaguely recall reading something about disabling OpenGL extensions, but I'm not sure if that's relevant anymore or how you would do it on an ATI card.
Anachronox will not start any more!

Oh, wow. I didn't even realize Gog had a forum made especially for each game. Thanks for that. I actually found this site through google while trying to troubleshoot it on my own so I thought I'd give it a shot on here... Especially since this is still largely an active forum. Thanks for the help.

If anyone else by chance knows how to solve this problem off the top of their head, by all means...

in the options renderer should be set to opengl not 3dfx
try renaming the anachronox exe (anox.exe ??? ) to mohaa.exe

The source for this may be standard "OGL extensions buffer" overflow.
Find the line gl_extensions: %s in ref_gl.dll and replace %s to %p.

As the radical solution - install Anachronox build 44, nGlide and use WickedGL renderer.
