hardware question

Ensure that you are using a real OpenGL driver than Microsoft’s GDI/D3D emulation layer. Microsoft, in their infinite wisdom don’t install OpenGL drivers by default. You have to download and install them yourself from Intel’s website.

printf("GL_VENDOR: %s
", glGetString(GL_VENDOR));

This will tell you which driver you are using (if it contains “Microsoft” you have a problem).

Hi, Stephan, thanks for the info. I tested that statement and the result was “Intel”. Is that what we’d like to see?

Yes.

I’d suggest checking for newer drivers on Intel’s website, but I don’t have any other advice to offer on the issue…
