G''day there, I was looking to get into pixel shading, and found the ''cg'' shading language library. But for some reason when i try and run programs that use simple bumpmapping or vertex shading etc... The say that my hardware doesn''t support it and runs in "VERY slow-mode". In other words the software is emulating it or whatever. I downloaded the latest drivers for my raphics card from nVidea and installed them. (I have a Geforce 4 MX card) and the drivers said they supported my card. So why can''t i make use of the new ARB extensions like GL_ARB_vertex_... and things like that? Is it my graphics card?! Or do i have to do something in the code or in the setup somewhere that says where or what these extensions are?! I don''t know what to do! I really hope someone can help me with this. It''s a real pain not being able to run these demos and tutes, i really want to get into shaders. MeeZ

You video card is a GeForce 2.5. Anyway you need a GeForce FX or Radeon 9500+ for CG fragment shaders.

Edit: Your card does support the GL_ARB_vertex_program but only in software.
