High level shaders vs low level shaders

[3DModelerMan]

I use opengl and I need shaders in my game, now my graphics card does'nt support high level shaders, what should I do?, if my graphics card does'nt support glsl, is there a chance it supports cg?, and if not where can I find software shaders?.
Thanks .

You can still write in glsl then use cgc.exe part of the cgtoolkit available for winodws and linux to make asrb code (lowlevel opengl shaders), cgc.exe can also do directx shaders to low level.
