gpu usage is nearly 100%

this is bad, should find fix

stop rendering loop when it is not needed would help a lot. just run render when music is playing.

it seems to work little bit better with glfw and it might be that this not actually a bug. maybe we should just close this for now.

[helgrima]

using glfwSwapInterval to limit framerate when music is not playing could provide solution to this

[helgrima]

if framerate is limited when music is not playing gpu usage drops dramatically. this also has side effect that limits framerate when traversing trough rocket tracks. clever way to detect that music is not playing and user is not traversing trough rocket tracks will be needed.
