   vertex/pixel shaders GPU
  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."C lets you shoot yourself in the foot rather easily. C++ allows you to reuse the bullet!"
