While we are on the subject of ST3C, does the third line of the conf ini open GL allow you to set it there?

[Render_OpenGL]
TexQual=3
TexMipFilter=3
TexCompress=0 Ie; if you changed it to 2 or 3 instead of 0?

Sorry doesn't help with your problem, but it's not worth making a new thread for it. (I know you can set it up in the set up exe)
