How can i check which version of opengl i use?

Opengl 1.3? You must use extensions for that, so I dont think it would work for him.

What do you mean you have to use extensions to use OpenGL 1.3? OpenGL 1.3 is the core and does not involve any extensions.

To check version, use glGetString(GL_VERSION).

i don’t want to use extension to use opengl.
i want to do bump mapping without any extension.

and thank you for the glGetString(…)

Yes, it is possible, but due to the fact that MS dont upgrade their DLL (opengl32.dll) you have to get the procAdresses for all the 1.3 calls via wglGetProcAddress and not via the .lib or the normal getProcAdress, but its still not extensions.
