OpenGL in ArchiCAD 8

What is OpenGL?

OpenGL is a fast display method for 2D / 3D-like elements developed by Silicon Graphics. It is optimized for fast interactive navigation among 3D polygons in a fancy and fast way. This makes it especially suited for professional CAD programs.

OpenGL Drawing Method Troubleshooting

If you are encountering a display problem or even a software crash, try the following methods:

To verify if the OpenGL display driver is the cause of your problem switch off the Open GL mode
(Options>Preferences>2D Redraw Options>Optimize drawing method for...)
If the problem is gone, but you'd still prefer the OpenGL drawing method:

Check whether the video card driver is set to use the default OpenGL settings.
Choose "Allow applications to control the antialising mode" in the driver configuration window.
Install the latest display driver for your video card. Some manufacturers' download links are available here.

Note: WHQL drivers are pre-tested by Microsoft and certified as stable versions. For maximal system stability we highly recommend these driver versions.
