Linux/OpenGL: ONLY DomIII does not run! Why?

[Chazar]

Doesn't work: If I bend the symbolic link ("ln -s source target") to

/usr/lib/libGL.so.1 -> /usr/X11R6/lib/libGl.so.1

(which,btw, were both links to libGL.so.1.2 in their respective directories), then Dom2 runs fast again without troubles, but Dom3 aborts with the same invalid pointer error reported by glibc that I described two posts ago... It prints a backtrace though, which I attach as a txt-file to this post.

However, I did not bend the link for libGLU.so.1, because I cannot find another libGLU -file anywhere else?

Thanks for the help! I understand that people here cannot fix particulars to my linux distribution, but I need at least know what questions I should ask elsewhere in forums concerned with my linux distribution, with the questions not being particular with Dominions. I mean, since other openGL games run, people elsewhere will just tell me to ask the game's developer. So that is why I wonder where Dominions is different...

in reply to Johan K:
the zbuffer switch only helped a tiny bit, but even in 640x480 with -xxx and all quality settings to "very low", the battle graphics benchmark is at ~2fps, whereas Dom2 runs at 14 fps with high battle graphics, best quality filter, and fullscreen 1680x1050.
