Well, depending on your computer, OpenGL could be faster than native draw modi. (That's not the case with Vue, mind.) OpenGL in Vue offers you anti-aliased lines and wireframes, and shaded viewports, i.e. objects can be displayed with shaded surfaces according to the lights in a scene or with default lighting. Also, you can work over a preview render in the 3D viewport--i.e. keep the last render displayed as a reference while continue your scene setup or lighting. Last but not least--and that's why I am happy about OpenGL finally working for me--you can import and display an image as a background for the viewports. This can come in VERY handy if you're modeling an object or a scene: just use the scan from a hand drawing or a photo as a new backdrop, and model around the sketch, or use the sketch as the layout for your scene setup. ta, -Sascha.rb
