What is the proper OpenGL initialisation on Intel HD 3000?

While your current implementation of OpenGL initialization appears correct, consider using a library that simplifies this process, such as:

• Loader libraries: These automate the task of loading the necessary OpenGL functions.
• SFML: SFML handles context and window creation, while GLEW handles OpenGL function loading (especially helpful on Windows).
• glfw: This library allows you to create OpenGL contexts and load OpenGL 3.2 functions.

Switching between different rendering contexts

Your use of wglMakeCurrent(hdc, hrc) for context switching is suitable. However, if problems persist, consider these alternatives:

• Context sharing: Create multiple contexts that share resources and textures, reducing the overhead of context switching.
• Storey/overlapped contexts: If you don't need to view multiple OpenGL contexts simultaneously, use this method to create separate contexts with overlapping pixels.
• Supported extensions: Check if your graphics card supports specific extensions that provide improved context management, such as WGL_ARB_pbuffer or WGL_ARB_multisample.

Additional considerations

• Your issue with creating multiple rendering contexts may be related to an Intel driver limitation.
• Some older Intel GPUs have been known to experience issues with multiple OpenGL contexts.
• It's worth mentioning that you may encounter bugs or limitations when using older graphics cards with modern OpenGL software.
