OpenGL 3.2 support (optional requirement)

If you are running the 3D option in CLOUDFLOW, your server needs to be equipped with a 3D capable video card which has at least 1.5 GB of VRAM available and has a driver installed with at least the OpenGL 3.2 API.

OpenGL and Windows Service incompatibility

Windows doesn't allow applications that are started via the service manager to access OpenGL. If 3D is to be used in CLOUDFLOW running on Windows, you can to start the CLOUDFLOW software from a computer start-up script.
