Why is Light2d on Android so slow?

Hi!

Why is the Light2d so slow on Android? Is that a general problem or am I doing something wrong? If I use just 3 lights (without shadow) the performance goes down! Without shadow lights should be just images with mixmode "add", right? Isn't that hardware accelerated?

If I add just Sprites with blend mode "add" there is no such performance impact. So what is wrong with Light2d? Can somebody explain that?

Thanks and Regards, Daniel

    Sorry for crosspost on Reddit! Seems important to me and I don't know yet on which forum is more activity.
    I have uploaded an example: http://noisefever.de/up/Marble.zip

    That is exactly what I would suggest you to do :D
    I think only Godot devs can help you with that.

    Light2D is slow in android and is slow in desktop system. But in desktop is less noticeable. Simply make a desktop project with a few lights and various mix modes and you should notice that is difficult to mantain 60 fps. Is not problem releated with android, is a problem releated with light2d performance and mix modes.

    I don't get it why it's so slow. Ok, RandomShaper explained it, but other games/engines/codeexamples/methods are faster (as far as I seen it). But I accept it. I have to :D
