I don't​ know why Google Earth exists. The satellite mode in maps is very good, doesn't depend on PNaCl, and is part of Google Maps, where it makes sense.

  There is no satellite view anymore, it's called "Earth". Not to be confused with Google Earth. And to disable the crappy 3D you have to go into the menu. What's funny is that if you disable WebGL then you get a much more usable version of Maps IMO.

    I love that 3d experience you call "crappy". To each their own, I suppose.

  Javascript has big performance limits which don't allow Maps to do everything that Earth does. The 3D engine in Earth does a whole lot of magic to get the visual quality that it has. In Javascript, you have to trade off everything to minimize your function call overhead into WebGL and try to pre-generate as much static content as possible. Earth has a much quicker access path to GL, which allows it to render more and higher quality visuals. Satellite mode without terrain can look fine in JS/WebGL. Once you start tilting the view and seeing terrain and buildings, the JS performance will be horrible pretty fast, and adaptive LOD streaming is hard due to the function call overhead. I worked on the Google Earth desktop app for a few years, so this isn't idle speculation. This new NaCL version seems to be nowhere near feature parity with the old desktop client, sadly. I hope it catches up, since I loved the historical imagery, for instance. The good news is that the desktop app still works if you want to see that.

    Thanks for the reply. I played with this new version and with Maps's Earth mode for a bit today, and to me they feel identical 3d-eise (except that the new thing only works in chrome, and I like Maps's UI better).
