    Exclamation Error running OpenGL with Unity program

    Hi there,

    I've been encountering this error when starting a Unity exe I created. Can anyone tell me where this might be arising from?

    Thank you.

    The problem is that all Windows versions come with OpenGL 1.1 by default, and the Kivy Framework that runs the Buffered VPN application needs OpenGL 2.0 support.

    The solution is pretty easy; all you need to do is upgrade your graphics drivers. For that, you’ll need to know what type of graphics card you have in your system.
