Jerome, Nicolas is actually right. There is absolutely nothing driver-specific about the extension. It's a pure API improvement and doesn't have anything to do with the hardware. There are no capabilities required, just ARB_vertex_program. Nicolas, Please test the attached patch. I have also enabled ARB_half_float_pixel and ARB/APPLE_vertex_array_object.

Sure we can report wrong informations but what's the point ? Cheers, Jerome </blockquote></div>
