Hi

I'll admit that I don't understand fully your comments but based on what you've said how does anyone go out and buy a desktop/laptop to develop opengl using vertex shaders?

I have a desktop running a 7 year old WinXP/Nvidia Quadro/OpenGL 2.1/GLSL version 1.20 that runs the program fine and a laptop purchased a few months ago wunning Win7/ATI Radeon/OpenGL3/GLSL version 3.3 that doesn't run the program.

How could anyone predict or expect this? And how can anyone develop code for such scenarios?

Thanks

Graham
