Some Crocodile Clips products feature 3D graphics that take advantage of OpenGL. OpenGL is an industry standard and is available on most computers purchased within the last four years, but it requires the correct graphics card drivers to be installed on your computer.
Most problems viewing 3D graphics, including performance issues, are caused by having no OpenGL drivers installed for your computer's graphics card.
Graphics card driver software is freely available from most manufacturer's websites. When updating your graphics card drivers, it is important that you use the software that is specifically designed for your graphics card.
Some users may also experience OpenGL problems when using multiple monitors or a projector if the display is set to be spread across both devices. To avoid this, set up both devices to show the same view.
