While opening the simple_texture patch in GEM examples I get these problems:
[glsl_vertex]: need OpenGL-2.0 (or at least the vertex-shader ARB-extension) to run GLSL
[glsl_fragment]: need OpenGL-2.0 (or at least the fragment-shader ARB-extension) to run GLSL
[glsl_program]: openGL-2.0 (or at least ARB shader extensions) needed for GLSL
I'm using a laptop running windows 7 and equipped with Nvidia Geforce 820m graphic card and the last version of PD extended (0.43.4)
Any idea on how I can solve this problem?
