Black Screen after intro

Sorry for the long time it took to make a reply, but here is the rundown of most OGL extension that are used. Also note that different quality modes require different shaders. Lower quality uses less extension

ARB_texture_rectangle
ARB_vertex_buffer_object
EXT_stencil_two_side or ATI_separate_stencil (there is fallback for this though)
EXT_texture_filter_anisotropic (only used when turned on)
ARB_multisample (only used for FSAA)
ARB_vertex_program
ARB_fragment_program (not used for low quality)
NV_register_combiners (only used for low)
ATI_fragment_shader (low only)

Thanks Thomas. I suspect ARB_vertex_buffer_object is the problem, I believe VBO support is still missing (incomplete?) in the free driver. All of the other extensions you listed (with the exception of NV_register_combiners and ATI_fragment_shader) are supported AFAIK.
