This wallpaper is not using OpenGL and the GPU. If you want the 3d version (runs much smoother on most devices) please have a look at Space Travel 3D Live Wallpaper.
A live wallpaper that takes you on a journey through space. Configurable from a classic 8-bit star field (well known windows screen saver) with pixel stars to 3d spheres in different colors or a star trek like warp speed where the stars turn to lines. Choose the speed, size, number of stars etc.
