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. More info on Wikipedia : OpenGL
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.
