Frequently Ask Questions.

You can’t download OpenGL itself, but you can download display drivers that include OpenGL. Check the version displayed by OpenGL Extensions Viewer. If it shows ‘GDI Renderer’, it means that something is preventing OpenGL from working. Sometimes, setting an environment variable with QT_OPENGL can resolve the issue.
Yes, it will work. The version number is the first set of figures in the version name, and in this case, it is 4.6.
This means that something is preventing OpenGL from working. For example, opening an OpenGL software remotely or through a virtual machine usually doesn’t work. Check OpenGL Extensions Viewer to see which version is installed, particularly the DirectX version. If you have DirectX 11, there is a good chance that OpenGL is compatible, but a software or resolution issue may be blocking it.
