Select "Auto" for opengl rendering gpu; generally select automatic mode for opengl rendering. The rendering will be automatically selected according to the actual hardware of the computer; if you want to specify, then specify the appropriate graphics card, because the graphics card is more suitable For rendering 2D and 3D vector graphics content, the support for OpenGL general computing API is stronger than that of the CPU.
#The operating environment of this tutorial: Windows 10 system, Dell G3 computer.
Opengl rendering gpu should choose automatic or graphics card?
automatic
1. Generally, you can choose automatic mode for OpenGL rendering , it will be automatically selected according to the actual computer hardware conditions when rendering.
2. If you want to specify, then specify the appropriate graphics card, because the graphics card is more suitable for rendering 2D and 3D vector graphics content, and its support for the OpenGL general computing API is stronger than that of the CPU.

OpenGL (English: Open Graphics Library, translation: Open Graphics Library or "Open Graphics Library") is a cross-language, cross-platform library for rendering 2D and 3D vector graphics. The platform’s application programming interface (API). This interface consists of nearly 350 different function calls used to draw everything from simple graphics bits to complex three-dimensional scenes. Another programming interface system is Direct3D only for Microsoft Windows. OpenGL is commonly used in CAD, virtual reality, scientific visualization programs, and video game development.
Highly efficient implementations of OpenGL (which take advantage of graphics acceleration hardware) exist on Windows, some UNIX platforms, and Mac OS. These implementations are generally provided by display device manufacturers and are very dependent on the hardware provided by the manufacturer. The open source library Mesa is a purely software-based graphics API whose code is compatible with OpenGL. However, due to licensing reasons, it only claims to be a "very similar" API.
Today, OpenGL is the most widely accepted API for processing 2D/3D graphics in the video industry. On this basis, in order to be used in the research of computer vision technology, it has spawned various computer platforms. of app features as well as many apps on your device. It is independent of the Windows operating system and operating system platform, and can carry out development and content creation in a variety of different fields. In short, it helps developers to implement software on PCs, workstations, supercomputers and various industrial computers and other hardware devices. Realize the development of high-performance, high-vision graphics processing software with extremely high visual requirements.
