My graphics card has hardware accelerator for OpenGL. Also, the lastest driver is istalled. However, displaying a graphic is still slow. In the "Program Option" dialog box, "Graphic" tab, is the "OpenGL - Accelerator" deactivated.
The OpenGL accelerator can be generally used for the color depth of 16-bit or 32-bit only.
In the Display Properties of Windows, set the color depth to True Color (32-bit) or to High Color (16-bit).
