------- Comment #2 from [EMAIL PROTECTED] 2007-07-06 16:40 PST -------
Now I immediately get to the SIGABRT:
(gdb) bt

This value of n looks odd.

In frame 45, I did:

shader\n// written by Forest 'LordHavoc' Hale\n\n// common definitions between

I will attach an archive with the GLSL shader that DP uses, and a version that
Mesa accepts without an abort (mainly by splitting expressions into multiple
lines and removing casts that only are necessary on nvidia cards to use half
precision floats). There seems to be a problem with the preprocessor too, but I
can't figure it out.
BTW, good news: Nexuiz works in Mesa with acceptable frame rates (about 60fps)
on 320x240 with r_showsurfaces 1 (textureless flat rendering). At the lowest
possible "real" settings, I get 7fps. Good work, now if you could get this up
to 15fps... doing a 320x240 r_showsurfaces 1 timedemo (tdem demo1)... resulted
in actually "just playable" performance:
1910 frames 56.9229441 seconds 33.5541324 fps, one-second min/avg/max: 21 34 50
