> Google uses texture mapped polygons instead of 3D Gaussians,

Time to switch I'd say...

Polygons are a poor fit, especially for trees and windows and stuff that needs to be semitransparent/fluffy.

I suspect the gaussians will compress better, and give better visual quality for a given amount of data downloaded and GPU VRAM. (the current polygon model uses absolutely loads of both, leading to a poor experience for those without the highest end computers and fast internet connections).
