That year should bring the long-awaited OpenGL ES 3.0 compatible renderer with state-of-the-art rendering techniques tuned to work as low as middle end handheld devices - without compromising with the possibilities given for higher end desktop games of course. Great times ahead for the Godot community and the gamers that will play our games!
