Re: [PyOpenGL-Users] access violation when calling glGenFramebuffers

[David V. <cod...@ha...>]

My best idea is that the Intel GPU Drivers on 64 bit systems will prefer 
to load at memory addresses above 4 gigabytes, while the other drivers 
will load at lower memory addresses. This is pretty much what I found, 
since the valid addresses returned by wglGetProcAddress on my system are 
above 4 gigs.
