I am running SolidWorks 2007 SP 3.1, I recently upgraded my computer video card to NVIDIA QUADRO FX 1500, worked fine except for Real View feature does not work. Solidworks video cards test website indicates that this type of video card supports realview. I am not working in large assembly mode so that shouldn't affect realview. A week later we bought NVIDIA QUADRO FX 3500 a more powerful video card, I installed that one but still real view function does not work. Am I missing something?
