OpenGL (Open Graphics Library) is an application programming interface (API) to Hardware graphics processing unit (GPU) for rendering 2D and 3D Vector graphics.
The OpenGL is comes along with Display driver and no need to install them separately.
To get optimized graphics performance in Operating Systems or Applications, the appropriate latest Display driver has to be installed. Since AMIDuOS often interacting with GPU, we are recommending to install latest display driver to get the seamless graphics experience in AMIDuOS.
The Display driver can be downloaded from GPU vendors(Intel, Nvidia or AMD) downloads/support page.
