3D examples don't work

[ludoke]

I'm trying to learn something from the 3D examples, but most don't work !

I have already noticed this and it is mostly due to the DirectX driver.

Just switch to OpenGL.

Compiler-Option -> Library Subsystem "opengl"

There needs to be a command to enable OpenGL in the source code, so we don't need to specifically manually enable it in the Options. That way it would work immediately when we copy/paste the examples.
