C# Question

vtkOpenGLExtensionManager Extension GL_VERSION_1_2 could not be loaded

I'm getting this error at runtime when launching my C# volume rendering program.
I saw that I'm not the only one, but still did not find any solution. I read that it could be a NVidia related error. But at first, I coded this program in C++ and everything worked well on that same computer (just different OS)

ERROR: In ..\..\..\..\vtksource-prefix\src\vtksource\Rendering\vtkOpenGLExtensionManager.cxx, line 393
vtkOpenGLExtensionManager (1210BD08): Extension GL_VERSION_1_2 could not be loaded.

I don't even know what details anyone might need to help me on this, so please ask for precisions if needed.

I saw that for some people, this error does not prevent their program from working. In my case, the rendering is all wrong, so I really need to fix that.

I'm using Kitware VTK Activiz.NET x86. GC: NVIDIA GeForce GTX 860M


I found a solution which is working, but I don't really know why

In my device manager, under GPU tab, I have :

> Intel(R) HD Graphics 4600
> NVIDIA GeForce GTX 860M

both of them where enabled, I just disabled the first one and now everything works well.

Does it mean I was never using my GeForce since the beginning?
