Google made Street View better, especially on mobile devices, by launching a new Street View renderer in the Google Maps JavaScript API. The new renderer uses WebGL (on browsers that support it) which results in a higher frame rate and better rendering, especially on mobile devices. On mobile devices, the old renderer would display a fish-eye projection of the image, whereas WebGL allows us to present a rendered sphere that looks as it would in reality. For example, the street in the image below is straight, but the old renderer made it look curved on mobile devices. Read more about other improvements.
