Phaser in 3D with Physics (yes, it works, using enable3d!)

You can’t expect to run it at 60fps on a old device, in a high resolution with antialias enabled.

I already wrote what you could do to increase the performance in post #21.

In addition you could also disable the shadows.

Most 3d games have a menu where you can adjust the graphics settings. Just add such a menu to your game and you are good to go.
