How To: Check the graphics card type and OpenGL version


OpenGL is an industry standard 3D graphics API. OpenGL 4.1 or later is required to run CityEngine 2019.1. For more information, refer to CityEngine 2019.1 system requirements. OpenGL drivers are usually installed together with the rest of the graphics driver and support software (such as DirectX).
