"Real-time visualisation and rendering are very demanding on the video card. As a good referenced point for the capabilities of your hardware, you may find PassMask Software's video card benchmark pages for high-end GPU's useful. A PassMark G3D mark of 2000 or more could be considered a general minimum performance requirement for Capture, but in practice, the actual requirements will vary a lot depending on how you use Capture."
Your card scores 1016 so if you are trying to open a big project, your card can not cope with the demands.
