Caddie uses OpenGL graphics libraries, so graphics cards specifically designed for OpenGL such as nVidia's Quadro or RTX ranges and AMD's Radeon range will give the best performance.
On board graphics should be avoided as these are generally designed to be used with general office software and not CAD or 3D programmes such as Caddie. If your computer has only an on board graphics processor, purchasing and installing a standalone graphics card will often greatly improve the display capabilities of your computer.
