I just rebuilt mesa to get the gallium softpipe:
glxinfo | grep renderer OpenGL renderer string: Gallium 0.4 on softpipe
Is that 32-bit Mesa or 64-bit though? Wine needs 32-bit, glxinfo typically uses 64-bit. The first couple of lines of WINEDEBUG=+wgl should tell you what Wine is actually using. I'm asking mostly because what you're reporting sounds suspiciously like https://bugs.freedesktop.org/show_bug.cgi?id=35373, which also explicitly mentions Civ 4.
A test-run with current wine.git master shows the same too dark graphics as seen before.
Should I open another bug report?
Yeah, that's probably better, provided the 32-bit stuff mentioned above is all correct.
