Optimizing LightmapGI for Android

Godot Version

4.4.1

Does anyone have experience optimizing LightmapGI for Android? I’m measuring performance, and there’s ~15fps lost when I add a LightmapGI and bake lights even when there are no light sources or environment. This is on a basic scene with a plane and a few low-poly trees.

Has anyone been able to add a basic LightmapGI setup without any significant loss of performance on mobile?
