I'm writing some modules using "DirectStateAccess" capabilities. If it's not supported, I made the necessary stuff.
On a customer laptop, I was able to create an OpenGL 3.3 Core Profile context. In a first call to glGetString(GL_EXTENSIONS), GL_EXT_direct_state_access was available.
However, GLEW_EXT_direct_state_access variable definitely equals false.
Subsequent call to wglGetProcAddress("glTextureParameteriEXT") returns a non null value though. And the functions glTextureParameterxx() seem available as well...
At this point, I wonder if I can rely on GLEW variables to check if an extension is indeed supported or not.
Oh, by the way, I made my tests with a "valid OpenGL context activated"...
