STELLARWINDOW use OpenGL heavily, you should use powerful video card for OpenGL 3D rendering. We recommend nvidia video cards than ATI video cards because nvidia cards seem to have better stability of the OpenGL rendering for STELLARWINDOW.

However, STELLARWINDOW has the Lite Mode that is designed for low-spec PCs such as net-book. The Lite Mode does not require high level of 3D rendering. On-chip video is enough for the Lite Mode.
