I've been doing shader with the extensions GL_ARB_VERTEX_PROGRAM and GL_ARB_FRAGMENT_PROGRAM, but I'd like to modernise a bit using the GLSL.
If I understand properly, I need the extensions GL_ARB_shader_objects, GL_ARB_vertex_shader and GL_ARB_fragment_shader to do so. I've been quite surprised to notice my GeForce FX 5900 with the latest driver (56.72) doesn't support those while my Radeon does.
I've seen in another topic somebody talking about those extensions on NV, so they most exist somewhere. Any clue?
