I am having problems with 3D model in OpenGL - Archicad Version 9. I just upgraded my graphics card to BFG GeForce 9800 GT OC 1gb. The model looks and moves great while navigating, but image disappears when static. I installed the latest Vista 64 bit drivers with no improvement. Thanks for any help you can provide.
